London, Museum Press / Science Fiction Club, 1953. First edition, first impression. Hardback. A very good copy. First British edition, preceded by the US Doubleday edition. An excellent novel, examining the interplay of communism and US society. Some chipping to the corners and spine tips, price-clipped. Some offsetting and a little foxing to the edges. Boards a bit dusty. [9226, Hyraxia Books].
