STAN LEE, CENTERFOLD (photograph by Eliot R. Brown)
When Stan Lee visited New York in January 1983, the editorial staff was at the peak of its yuk-yuk, hand-buzzer giddiness. They’d been shooting photos of each other in superhero costumes for some of the covers—several staff members appeared on the cover of the last issue of SPIDER-WOMAN—and now they were putting together a comic that consisted wholly of photos of intra-office hijinks. They wanted to include Stan the Man. Lee, the original ringmaster, jumped at the chance to pose for a nude centerfold. Marvel staffers photographed Lee with an oversize comic book covering his private parts; soon after, they received a call from his assistant in L.A. “Stan is wild,” said the assistant. “He should not have been naked for your centerfold. Please. Don’t.” (A Hulk costume was later superimposed over Lee’s body in postproduction.)

UPDATE: Photographer Eliot R. Brown adds, “Stan indeed kept his fire-engine-red bikini briefs on—very business-like, I must add. You’d have thought he did this every day.”
