The Fundamentals of Sword & Planet, Part I: Don Wollheim, Edwin L. Arnold, and Otis Adelbert Kline
Swordsmen in the Sky (Ace, 1964). Cover by Frank Frazetta Swordsmen in the Sky, edited by Donald Wollheim If our genre has a holy grail to find, this would be it. I read this collection as a kid. Found it in our local library. And loved every single story in there. Took me a while to find a copy as an adult but it’s one of my pride and joys.
