Superman #171

In "Superman's Sacrifice!", the Man of Steel is stranded on a distant world bathed in a red sun, stripped of his powers and reduced to the weakest man alive—only to be attacked and robbed by a primitive warrior who takes his iconic suit. With his strength gone and his identity stolen, Superman must rely on his wits and the courage of his allies when Jimmy Olsen and Lois Lane arrive in a spaceship to rescue him. Written by Edmond Hamilton and illustrated by Al Plastino, with a striking cover by Curt Swan and George Klein, this 1964 classic redefines Superman’s vulnerability in a story that tests his resolve like never before.
