Superman #108

The cover of this September 1956 DC issue tells its own delicious story: Superman stands trapped behind prison bars in full costume, caught in a bind of his own making, while two sharp-eyed female police officers in blue uniforms stand just outside the cell, one remarking that the jammed lock has given them the perfect chance to confirm their suspicion that Clark Kent is Superman. Al Plastino's clean, expressive linework makes the Man of Steel's anxious internal monologue — visible in his speech bubble — instantly relatable, turning a classic secret-identity dilemma into a wonderfully tense cover moment. Featuring the story "The Girl Cops of Metropolis" and interior work by Wayne Boring and Stan Kaye, plus details for a Giant 5000 Prize Contest, this ten-cent issue packs a lot of charm into one irresistible package.
