In "The Week That Clark Kent Lost His Memory!", Clark Kent’s world turns upside down when a shard of Red Kryptonite wipes his mind, leaving him adrift in a life he no longer recognizes.

Written by Robert Bernstein and illustrated with vibrant clarity by Ramona Fradon, this 1960 adventure blends sci-fi mystery with a touch of superhero vulnerability, all framed by Curt Swan’s iconic cover and Stan Kaye’s crisp inks.
