“Promotional art for Captain America: Civil War has been released online, providing another look at Iron Man’s new armor for the film.
As Gonzales mentions, some fans have noticed that the armor bears a resemblance to the “Bleeding Edge” Iron Man armor from the comics, seen below. The notion is somewhat circular, since the Bleeding Edge armor, which debuted in Invincible Iron Man #25 in 2010, was inspired by the armor from the first Iron Man movie.”
