Action Comics #430

Celebrating 35 years as "The World's Greatest Super-Hero," Action Comics #430 (December 1973) presents a genuinely intriguing cover by Nick Cardy: Superman streaks through a nighttime cityscape above apartment building 344, thinking "Time for me to resume my secret identity as Clark Kent!" — while a mysterious purple ape-like creature flies alongside him declaring it's heading out "on the prowl." A doorman below looks on, blissfully unaware, and the cover's bold teaser — "Which one of Superman's neighbors leads a secret life as a monster?" — promises the kind of suspenseful, dual-identity storytelling that made Bronze Age DC so entertaining. Rounding out the issue is a bonus Atom feature, making this a solid double-header from DC's 1973 lineup.
