“Clark Kent's Biggest Day!”

In "Clark Kent's Biggest Day!", Superman—dressed as the devil for a costume party—uses his disguise to outwit two notorious crooks he's been tracking. Written by Jerry Siegel and brought to life with Al Plastino’s expressive art, the story blends clever deception with classic superhero flair. The cover by Curt Swan and George Klein captures the moment with a striking, devilish twist.
