New York, Putnam, 1961. First edition, first impression. Hardback. A very good copy. An important milestone in science fiction and modern literature. The jacket has some heavy chipping to the top and bottom of the spine and a few short tears. The forecorners are similarly worn, but to a lesser extent. Rear plate a touch toned. Happily the spine remains unfaded. The book is nice with some light bumping to the spine tips. [9399, Hyraxia Books].
