Action Comics #297

From 1963 comes this tension-packed issue of Action Comics, featuring a cover by Curt Swan and George Klein that drops you right into a heated confrontation: Superman, still dressed in his Clark Kent suit and glasses, pleads urgently with a sharply dressed man who clutches what appears to be a document revealing his secret identity, while a stunned Perry White looks on nearby. The story title — "The Man Who Betrayed Superman's Identity!" — promises exactly the kind of high-stakes drama that made Silver Age DC storytelling so compelling. Writer Leo Dorfman and artist Jim Mooney deliver the interior adventure, and there's even a bonus Supergirl story tucked inside for good measure.
