For the Fantastic Four's 20th anniversary in 1981, artist John Byrne packed a huge cover with almost every major hero at the company at the time, and, of course, Stan Lee. While the story inside is serviceable (it does feature Dr. Doom, after all) this issue is much more noteworthy for its front image.

John Byrne came onto the book like a hurricane in the ‘80s and transformed the team from a vapid Lee/Kirby parody into an incredibly nuanced foursome backed with real emotion and grounded stories. But every once in a while, Byrne allowed the team to have a little fun, and issue #236 is a prime example of the diversity that he brought to the book, which later became the norm for the title.
