This week's Captain America: The End #1 ended the issue with a credits page that mistakenly credited Stan Lee as co-creator of the titular hero.
While the book reads that "Captain America created by Stan Lee and Jack Kirby," it was actually Joe Simon and Jack Kirby who created the character. Lee was not yet working in comics at the time and actually didn't make his comic book debut until Captain America Comics #3 with a back-up prose story.
Captain America: The End's writer/artist Erik Larsen was informed of the error Tuesday on Twitter, replying "Sigh. Joe Simon and Jack Kirby creates Captain America."
The one-shot's editor, Jordan D. White, replied to that saying "Yeah—it was an embarrassing mistake, but nothing we can do at this point but apologize."
The publisher plans to correct error in the digital edition and for any future printings and collections.
