London, Hodder & Stoughton, 1937. First edition, first impression. Hardback. A very good copy. The first UK edition, preceded by the US edition of 1936, and the Blue Book magazine issue of 1935 (as Kioga). A Tarzan-like, which was filmed in 1938 as a 12-part serial. The UK issue is scarcer. A number of closed tears, the longest around 50mm, each has been fixed with tape to the jacket reverse. Some rubbing, creasing and edge wear elsewhere. Some bumping to the spine tips, a little dustiness to the top edge, and some offsetting to the endpapers. [11964, Hyraxia Books].
