The Adventures of Rex the Wonder Dog #11

In "Rex, Dinosaur Destroyer!", a 1953 DC adventure, the atomic age collides with prehistoric wonder when Major Dennis, Danny, and Rex stumble upon a newly exposed lost valley after a bomb test in the American Southwest. With a Tyrannosaurus Rex on the rampage and a second explosion imminent, the trio flees into a hidden world teeming with dinosaurs—only to face the terrifying aftermath of science and time unraveling. Written by Robert Kanigher and brought to life with dynamic art by Gil Kane and Sy Barry, the cover by Kane and Barry captures the chaos of a world turned upside down.
