Superman #104

A purple-costumed alien stands before a viewing screen displaying Clark Kent dramatically revealing his Superman costume, while a group of wide-eyed observers — labeled "Miss Earth Venus" and "Saturn Neptune" — look on in apparent astonishment. The cover tagline promises "The Super-Family From Out of Space," suggesting that these extraterrestrial visitors have somehow uncovered the Man of Steel's secret identity. Wayne Boring's pencils and Stan Kaye's inks give the 1956 scene a wonderfully crisp, Silver Age charm that captures DC's flair for imaginative, cosmic-scale storytelling.
