From Beyond the Unknown #12

Joe Kubert's cover for this September 1971 anthology pulls you straight into a collision of eras: a wild-haired, loincloth-clad primitive man rides a massive pterodactyl as modern military jets swoop in and missiles streak through a lurid yellow sky. It's a genuinely striking image — prehistoric versus contemporary, raw sinew against cold steel — and it perfectly sets the pulpy, imagination-first tone promised by the five stories inside. With tales ranging from "The Dawn-World Menace!" to "Mystery of the Runaway Meteor!," this quarter-priced DC anthology delivers exactly what its banner promises: stories to stagger the imagination.
