New York, Appleton Century, 1941. First edition, first impression. Hardback. A very good copy, in the jacket. Oswald Train's copy, with his plate to the front pastedown. "A future war tale, published just prior to the American entry into World War Two; here, the US declares war first, and naval battles focus on Panama and elsewhere." [SFE, Clute]. Spine faded, some light wear to the edges, but overall very nice. [11959, Hyraxia Books].
