In "Anything— For the Cause!", Tony Stark faces a rare personal test when he intervenes to save Big Joe's little sister during a high school football game, stepping in to protect a civilian in a moment of unexpected danger. Written by Allyn Brodsky and brought to life with dynamic art by Don Heck and Chic Stone, this 1970 issue captures Iron Man’s resolve under pressure, with Sal Buscema’s cover highlighting the stakes.
