Originally published in 1971, this story turned Superman's status quo on its head by featuring a story in which all Kryptonite was destroyed! But that leaves The Man of Steel anything but invulnerable as his powers slowly begin to fade and a doppleganger Superman arrives on the scene with strange powers of its own. Available now in softcover, this volume contains SUPERMAN #233-238 and #240-242 and contains a momentous story for the Man of Tomorrow that you won't want to miss!
