We've seen Iron Man -- and his suit -- evolve quite a lot over the years, but in a new series of variant covers that Marvel calls "Iron Man By Design," you're going to see Tony Stark in a variety of historical roles where you've probably never imagined him before: caveman, Roman Legionnaire, samurai, conquistador, and cowboy, among others. The variant covers run through major Marvel titles ranging from "Deadpool" and "Amazing Spider-Man" to the X-books, and we've got them collected in a gallery running after the jump!
