About this Issue

Action Comics #391 holds a place in Silver Age-to-Bronze Age transition history as part of the early Super-Sons cycle, an unusual corner of DC's "imaginary story" tradition in which Superman and Batman are depicted as fathers grappling with underachieving heirs. The lead story—in which Superman permanently strips his fourteen-year-old son's powers using Gold Kryptonite—represents one of DC's more strikingly bleak "imaginary" parenting narratives, and the issue later received retroactive placement in the multiverse when Crisis on Infinite Earths: The Compendium designated it as occurring on Earth-391. The Legion backup, concluding a two-part Dark Circle espionage arc, is notable for centering Element Lad as the mission's decisive hero and for publishing the results of an in-comic Legion Leader election—an early example of reader-participation continuity that gave Mon-El the top post and Element Lad the deputy role.

In "The Punishment of Superman's Son!", young Jo faces the consequences of his reckless use of superpowers, prompting Superman to make a difficult decision—using gold kryptonite to strip his son of his abilities. Written by Robert Kanigher and brought to life by Ross Andru’s dynamic art and Mike Esposito’s inks, this 1970 classic explores the strain of responsibility through a heartfelt, high-stakes father-son moment. The cover by Curt Swan and Murphy Anderson captures the emotional weight of the moment with striking clarity.

History

The issue went on sale June 30, 1970, with an August 1970 cover date, under editor Mort Weisinger and assistant editor E. Nelson Bridwell—one of Weisinger's final editorial cycles before Julius Schwartz took over the Superman titles. The lead story was written by Robert Kanigher, penciled by Ross Andru, and inked by Mike Esposito, with Curt Swan and Murphy Anderson producing the cover; pencil and ink credits for the lead were not widely known at the time and were only confirmed in the letters page of the later Action Comics #395. Kanigher deliberately withheld the identity of Superman's wife—directing that her face appear only in shadow and that she wear a blonde wig—a storytelling choice that became a defining, much-discussed quirk of the entire Super-Sons sub-series.
