Action Comics #429

A dossier labeled "Life-File of Superman alias Clark Kent" dominates this 1973 cover, and the Man of Steel himself is leaning in, finger pointed, demanding to know how someone could possess every secret of his life — right down to the exact moment of his death. Seated across from him is a shadowy figure at a desk, the tension between them practically leaping off the page in Nick Cardy's sharp, dynamic cover art. Rounding out the issue is a backup feature starring the Human Target, making this a genuinely packed installment of one of DC's longest-running titles.
