My Greatest Adventure #21

Few 1958 anthology covers capture the stakes of interplanetary jousting quite like this one: two riders mounted on fearsome dragon-like creatures charge each other with lances, while a flying saucer hovers in the background and a desperate thought balloon warns that the whole solar system hangs in the balance. Bob Brown's cover art crackles with pulpy energy, pitting a human challenger against a blue-skinned alien champion in a contest that feels both thrillingly strange and oddly chivalric. Inside, Henry Boltinoff delivers the featured story alongside "We Were Doomed by the Metal-Eating Monster" — a solid double reason to track down this ten-cent DC gem.
