London, Ernest Benn, 1928. First edition, first impression. Hardback. A near fine copy. Signed by the author without inscription. A fantastic work of science fiction wherein a mad scientist transplants genius brains into athlete's bodies. The scientist is controlled by the Soviets who have a bunch of hi-tech aircraft and a dystopian island (thanks to Bleiler and Cummins' for the description). A little bumping to the corners and spine tips, but overall in fantastic shape. A great book. [10902, Hyraxia Books].
