New York City: Ace Books, 1955. First Edition, Thus. Soft Cover. Very Good. Ed Valigursky. Vintage Paperback Ace D-110. Beautiful Special Edition, published separately from the ACE Double, also D-110, that was published with Poul Anderson's "No World of Their Own". No Month, 1955. $.25 cover price. Square, tight, and clean throughout with quite mild interior toning. A bit of edge-wear and rubbing and a short, shallow corner crease. Still, a fresh, bright example with no chipping or tears.
