All-American Comics #75

From a 1946 DC publication, All-American Comics #75 sends the Green Lantern soaring through a simulated cosmos inside a planetarium, his cape streaming dramatically as he confronts a group of tumbling villains amid the machinery and star-projectors of the exhibit. Paul Reinman's cover captures that unmistakable Golden Age energy — a hero at full flight against a backdrop of planets and celestial light, with Hop Harriigan keeping watch from his portrait inset at the upper left. Headlined with the promise of "Adventure in a Planetarium," this is a wonderfully imaginative slice of 1946 superhero storytelling.
