In 1978, Marvel’s Brooklyn warehouse got broken into and ransacked. But here’s the shocking part: the thieves scattered artwork all over the floor and left without taking anything. Why? Because in 1978, nobody thought comic art was valuable enough to steal.

By the mid-1980s, everything had changed, and Marvel’s security hadn’t.

Jim Shooter’s Account:

Marvel’s Editor-in-Chief at the time, Jim Shooter, described the warehouse conditions: “This warehouse was a dump! It was completely unsafe; anybody could break in there.”

In 1978, after the break-in scare, Shooter demanded all artwork be moved to his office - the only secure location in the building. “You should’ve seen it. It was me in a little corner, and wall-to-wall files full of art, because my office was the safest place in the building. You had to go through three doors to get to my office: The front door, the door to the editorial suite, and then my door, and I was the only one who had a key.”

When Marvel moved to new offices around the end of 1979, the art went to a “brand new state-of-the-art safe warehouse”—except one box that mysteriously ended up in the Marvel lunchroom.

The Catastrophic Losses:

Shooter’s assistant Johnny reported: “There were several floods, a couple of fires, rats, mold and thefts that wiped out a lot of old art. Johnny got back less than 55% of his work.”

If you have bought any old Marvel artwork, Shooter warned, “you may have bought stolen goods.”

While the Louvre thieves are amateurs, Pete Koch executed what may be the largest art theft in American history, and got away with it.

The Scope of the Theft:

According to industry sources: “Pete Koch stole all of the Ditko ASM’s except for two issues (one of them incomplete) that was already with Steve D at the time that Pete was arranging for the art to be stolen from the Marvel warehouse.”

“To this day he still has several complete issues including #1, 2, 3 and 4. He never had the AF 15.”

The Value:

“If you total up all of the values of the key Ditko and Kirby books, they would be well into the hundreds of millions of dollars. I believe that the Spidey 1-4 are probably worth five million dollars. What about all of the FF’s, Hulks, Avengers, X-Men, JIM, TOS, TTA, and so on…”

Industry experts believe Koch’s theft constitutes “the largest art theft in American history” when you calculate the current market value of what was taken.

The Current Status:

“There is not one clean Ditko ASM page out there in the marketplace. All should have been returned to Steve.”

Every Amazing Spider-Man page by Steve Ditko that appears on the market has questionable provenance. Yet collectors continue buying them for tens of thousands of dollars, knowing they’re likely stolen property.

Jack Kirby’s missing artwork represents the most documented (and most heartbreaking) case of the Marvel art theft epidemic.

The Numbers Don’t Add Up:

If Jack Kirby drew 10,000 pages during the 1960s (a conservative estimate given his Fantastic Four output alone was 2,000+ pages), why did he only receive approximately 2,000 pages when Marvel “returned” his art in 1987?

The math is simple and damning: 8,000 pages disappeared.

The Theft Timeline:

According to researchers who’ve compared the Vartanoff inventory (a comprehensive catalog done in the mid-1970s) with pages returned to Kirby: “The large scale theft took place in the ‘80s. Any books in Marvel’s possession in 1980 which Kirby did not receive a share of were stolen some time between 1980 and 1986.”

That’s a six-year window when thousands of pages walked out of Marvel’s warehouse and into private collections.

Where the Art Went:

Some art was used by Marvel to solidify business deals. Some was gifted to business contacts. Some was reportedly discarded. Some was dispersed to various inkers. Some was used as payment for services rendered. Some disappeared from the Marvel offices/warehouse. And some was returned to Kirby and subsequently re-sold to fans.

“Sales coming from the Kirby’s themselves were largely cash transactions and no paper receipts were ever issued. So virtually nothing today has a proof of sale or a proof or original provenance.”

-----

The tragedy is that much of the art that later became worth millions was initially treated as worthless trash.

The Garbage Culture:

Jim Shooter described the 1960s attitude: “In the 60’s, no one gave a damn about original artwork. Artwork from several Legion of Super-Heroes issues were given to me at various times. I felt that it was wrong that I should have that artwork. I called Curt Swan and offered to send it to him, its rightful owner, in my mind. He said if I wanted it I should keep it because he had no room for it, and he would only throw it away.”

“It was common practice in the ‘60’s at both Marvel and DC to give original art away to fans coming through on tours, fans who wrote good letters or any damn fool who wanted the stuff. Nobody cared. Nobody objected.”

The Prince Valiant Story:

“It is legend, but true, that at King Features, on rainy days, they would throw Hal Foster Prince Valiant (and other) original pages on the floor to soak up water.”

Pages that would be worth $100,000+ each today were literally used as floor mats.

The Winnipeg Art Gallery Sale:

In 1973, The Winnipeg Art Gallery borrowed approximately 50 works directly from Marvel Comics for an exhibition called “The Structure of the Comic Book.” According to later investigations, Marvel sold original art to the gallery during this period—art that should have been returned to creators.

Some of the most valuable comic art in existence was rescued from Marvel’s dumpsters by people who had no idea what they had.

The Dumpster Diving Gold Rush:

Industry veterans report that janitors, mailroom workers, and random passersby found Kirby, Ditko, and other legendary artists’ pages in Marvel’s garbage and kept them.

Some eventually discovered what they had and sold pages for life-changing amounts. A single Jack Kirby page from Fantastic Four #1 could sell for $50,000-$150,000 today. Pages from Amazing Fantasy #15 (Spider-Man’s first appearance) would be worth $200,000+ each if they existed.

The Provenance Problem

Today’s collectors face an impossible ethical dilemma. If you own a page of 1960s Marvel art, how do you know it was legitimately sourced?

“How do you know the dealer you bought it from — even if it was 30 years ago — got it through legitimate means? Would you want to give that page up? Would you want to get served a letter from Disney/Marvel legal?”

“Might be a good idea to hide the fact from the public that you own it. Take it down off the internet, keep it in your portfolio or hung framed on your wall, and never boast about it again. Stay quiet and they might overlook you for now.”

-----

Marvel used its work-for-hire contracts to justify keeping (or not recovering) stolen art.

The Legal Shield:

When artists demanded their artwork back, Marvel claimed the art was “work for hire” and therefore belonged to the company as a financial asset. Corporate counsel argued the art couldn’t be disposed of “with no benefit to the stockholders of a publicly traded company.”

The Kirby Hostage Situation:

When Jack Kirby tried to get his artwork back in the 1980s, Marvel demanded he sign a release form giving up all rights to characters he’d created—a requirement imposed on no other Marvel freelancer.

The company literally held his art hostage until he agreed to sign away any claims to characters like Fantastic Four, Thor, X-Men, and dozens of others.

The Insurance Policy:

At a Comic-Con “Marvel Then and Now” panel, Editor-in-Chief Jim Shooter stated unequivocally about original art: “We own it entirely.”

This ownership claim served as legal cover for Marvel’s failure to recover stolen art or pursue theft investigations. If Marvel owned the art, then stolen pages becoming the company’s “problem” to solve, and Marvel chose not to solve it.

-----

Fifty years later, stolen Marvel art continues trading hands for six figures in a black market that operates in plain sight.

Current Market Values:

The Provenance Fiction:

Sellers and dealers have developed elaborate provenance stories:

Most of these stories are impossible to verify and many are outright fabrications designed to launder stolen property.

The Collector’s Dilemma:

“If you own a page of Kirby art from Marvel in the 60s, how sure are you that what you own was legitimately sourced?”

The answer: you can’t be sure. And that uncertainty hasn’t stopped pages from selling for hundreds of thousands of dollars at auction.

For Collectors:

For Artists:

For Publishers:

For the Market:

The Louvre heist will dominate news cycles for weeks. Investigators will track the thieves. The stolen art will be recovered or remain infamous forever. Justice, in some form, will be pursued.

The Marvel art theft - worth hundreds of millions, involving 10,000+ pages, spanning decades - operates in plain sight with no investigation, no recovery efforts, and no justice for the artists whose life’s work was stolen.

Pete Koch reportedly still has complete issues of Amazing Spider-Man #1-4 by Steve Ditko, worth millions. Everyone in the industry knows this. Nothing happens.

Thousands of Jack Kirby pages that should have been returned to him are hanging in private collections, sold through dealers, and traded in back rooms. Everyone knows this. Nothing happens.

The difference between the Louvre heist and the Marvel art theft? The Louvre theft is treated as a crime. The Marvel theft is treated as business as usual.

That’s the real scandal.

This week’s spotlight: Amazing Fantasy #15, Page 11 - Spider-Man’s origin

The Story:

Amazing Fantasy #15 (August 1962) introduced Spider-Man to the world. Steve Ditko drew 11 pages telling the origin story that would define modern superhero comics. Those pages should be among the most valuable comic art in existence.

They don’t exist in the market. Not one page from Amazing Fantasy #15 has been sold at public auction. Ever.

Why?

Two possibilities: Either the pages were destroyed/lost, or they’re in private collections with owners who know they’re too hot to sell publicly.

Estimated Value If They Appeared:

The Provenance Problem:

“There is not one clean Ditko ASM page out there in the marketplace. All should have been returned to Steve.”

If Amazing Fantasy #15 pages ever surface, their provenance will be immediately questioned. Who had access? How did they get them? Why haven’t they surfaced in 60+ years?

Why It Matters:

The absence of Amazing Fantasy #15 pages from the market is the most tangible evidence of the Marvel art theft scandal. The most important pages in Marvel history have disappeared, and everyone knows they were likely stolen.

That’s not collecting. That’s concealing stolen cultural artifacts.
