In the early days of Marvel Comics, they did a lot of little things to try to build an kind of club-house atmosphere, including a variety of feature pages, one of which was having Jack Kirby draw mini-posters of some of his characters.
Right from the second issue of the Fantastic Four they started a series of full-page pinups featuring each of the team so you could cut your comic up and hang it on the wall. And we did. We tore out pages, cut out trading stamps, filled in puzzles and generally savaged so many comics while reading them to scraps. (Psst! Hey! Collectors! That's why those old comics are worth so much money. All these new #1 events you're investing in? Good luck with that.)
Anyway, let's look at those PinUps of each of our team:
