Superman #148

What a delightfully chaotic cover from Curt Swan (pencils) and Stan Kaye (inks)! The scene depicts a prison yard gone wonderfully haywire, where multiple figures in full Superman costume — apparently transformed prisoners — fly, smash, and cause mayhem while a guard looks on in bewilderment. A speech bubble announces the culprit: the fifth-dimensional imp Mr. Mxyzptlk, whose magical mischief has turned every inmate into a Superman, setting up what promises to be a genuinely fun puzzle for the Man of Steel. Featuring Jerry Siegel's writing and Curt Swan's interior art, this October 1961 issue captures Silver Age DC at its most charmingly inventive.
