Wonder Story Annual.  Vol. 1, No. 1,  1950. NY: Best Books, 1950.  "The Onslaught from Rigel" by Fletcher Pratt; "The Eternal Man" by D.D. Sharp; "The Robot Aliens" by Eando Binder; "The Derelict of Space" by William Thurmond and Ray Cummings; "The Moon Devils" by John Beynon Harris; and "Exiles of Mars" by Frank K. Kelly. Light chipping along the edges; the poor quality paper is barely discolored and still flexible. Bright and very good.
