London, Muller, 1960. First edition, first impression. Hardback. A very good copy. Association copy inscribed by the author(s) to fellow SF writer William F. Temple. The signature appears to be in two inks, and two hands, so presumably the inscription is by Newman and the name Kenneth by Bulmer - which makes sense. Jacket a little ragged and grubby, with foxing to the reverse. A little foxing to the endpapers. Illustrations by Arthur Thomson [9684, Hyraxia Books].
