“It was a freak of nature that this book was saved,” Mr. Fishler said.
On the cover and seven of the pages, Mr. Jacquet wrote how much his company owed artists including Frank R. Paul, who was paid $25 to illustrate the cover, Mr. Fishler said.
Had the book left the publisher’s office, it would have sold for 10 cents in 1939, or a little over $2 today. The publisher printed 80,000 copies in October 1939 and 800,000 the next month, according to comics.org.
Mr. Chambliss said that comic books from this time were often printed on pulp paper, a low-quality material that was not meant to last.
The copy passed through several hands from the time it was discovered in the file cabinet, the location of which was unclear. In 2003, the copy fetched as much as $350,000, according to itsjustallcomics.com.
Owning the pay copy of Marvel Comics No. 1 would be like owning a first-edition Charles Dickens novel in which he documented his royalties, said Douglas Wolk, who has read all 27,000 Marvel comic books and summarized them into a single narrative for his 2021 book, “All of the Marvels.”
Over the past few years, old comic books have skyrocketed in price, Mr. Fishler said. They may become even more valuable as more comics are adapted into movies.
