Mysteries of Unexplored Worlds #19

In "The Green Unknown," a Venusian fugitive fleeing the ecological ruin he caused on his home world brings his destructive cloud machine to Earth, only to be captured by interplanetary enforcers tracking his trail. Left behind, his device is repurposed by Earth’s scientists to generate life-saving rain and end a crippling drought. Written by Joe Gill and illustrated by Charles Nicholas with inks by Sal Trapani, this 1960 Charlton classic features a striking cover by Steve Ditko.
