Superman and Spider-Man

In 1981, Warner Books published the first intercompany crossover between DC and Marvel, bringing together the Man of Steel and the Wall-Crawler in a single prestige-format issue. Written by Jim Shooter and Marv Wolfman with art by John Buscema, this landmark one-shot sees both heroes—and their supporting casts—team up against a dual threat from Lex Luthor and Doctor Doom. As the inaugural meeting between the two publishers' flagship characters, it set the template for the crossovers that would follow, making it a historic piece of comic book collaboration.
