From Beyond the Unknown #19

From Beyond the Unknown #19 delivers exactly what DC promised with its tagline "Stories to Stagger the Imagination" — and Mike Kaluta's cover makes good on that pledge. A Neanderthal man bursts through what appears to be a museum display case (labeled "Neanderthal Man, 70,000 B.C. to 40,000 B.C."), firing green radiation beams at a modern man in a yellow jacket who cries out that the strange radiation is turning him into a caveman too, while a woman recoils in alarm beside him. Three anthology tales are advertised — "Return of the Neanderthal Man!" (by Gardner Fox and Carmine Infantino), "Paul Revere of Time!", and the Star Rovers story "Who Went Where — and Why?" — making this 1972 issue a satisfying package of science-fiction imagination for twenty cents.
