1940's novella: "Skeleton Men of Jupiter" by ERB

Thanks to the blog Hairy Green Eyeball 3, you can read crisp jpegs of “Skeleton Men of Jupiter,” a science fiction novella written by beloved pulp author Edgar Rice Burroughs with cover art and interior illustrations by J. Allen St. John, as it was originally published in the February 1943 issue of Amazing Stories magazine. 

“From distant Jupiter came a weird band of abductors,

the first move in an evil plan for the subjugation of Mars.”
