First edition thus. The book is identical to the US first, giving New York as the Publishing address. However the dust jacket lists Thomas Yoseloff Ltd, New Bond Street, London. Much scarcer than the American edition, which was a simultaneous isse. A very good book invery good dust jacket (rear board slightly bowed, slightly slanted) Jacket has been misfolded and has light loss (1/2 inch X 1/2 inch at rear, near base of spine).
