London, Rich & Cowan, 1937. First edition, first impression. Hardback. A very good copy. An uncommon science fiction novel. Presumably the R&C file copy given the pencil note requesting the book be returned. The jacket has some wear to the edges, a little fading to the spine, some soiling and a chip to the rear. Boards a touch lightened and soiled, top edge dusty and some foxing to the foreedge. [9858, Hyraxia Books].
