Ace Books, paperback original. Two identical printings, 1964 (cover code F-311 and 0.40 cover price) and 1969 (cover code 79276 and 0.60 cent cover price).

An anthology of stories originally published between 1933 and 1951. This book was something of a harbinger of the sword-and-sorcery boom that was only a few years away from beginning. An important book for the fan and collector. The stories are:

"Swordsman of Lost Terra" by Poul Anderson (from Planet Stories, November 1951)
"The People of the Crater" by Andre Norton (from Fantasy Book, July 1947)
"The Moon That Vanished" by Leigh Brackett (from Thrilling Wonder Stories, October 1948)
"A Vision of Venus" by Otis Adelbert Kline (from Amazing Stories, December 1933)
"Kaldar, World of Antares" by Edmond Hamilton (from The Magic Carpet Magazine, April 1933)

This is a hugely influentialbook that looms large for SF and fantasy fans as the first true science fantasy anthology in the spirit of Edgar Rice Burroughs.
