“Past Imperfect”

In "Past Imperfect," John Byrne crafts a mind-bending dive into time and identity as the Time Trapper reveals the origins of the Pocket Universe. With Superman and Superboy setting aside their differences, the Legion and Superboy launch a desperate pursuit to confront the enigmatic force behind the deception—art by Byrne, with inks by Byrne and Keith Williams, colors by Tom Ziuko, and lettering by John Costanza. The cover, also by Byrne, captures the moment of revelation with sharp, dynamic precision.
