Lawrence Person's Futuramen

Like the Fletcher Pratt book I bought a few months back, here’s a difficult signature I found cheap:

(Smith, Cordwainer) MacNair, Harley Farnsworth. The Real Conflict Between China and Japan. University of Chicago Press, 1938. First edition hardback, a Very Good copy with spine and page blocks slightly grubby, lacking a dust jacket (possibly as issued). Formerly Paul M. A. Linebarger’s copy, with his signature, “Duke” and “1938” written at the top of the front free endpaper. Linebarger is most famous for writing science fiction under the pen name Cordwainer Smith (as well as Carmichael Smith and Felix C. Forrest). He was also a renowned Sinologist whose father was one of the chief advisors for Chinese nationalist leader Sun Yat-Sen (indeed, I also own a copy of Linebarger’s non-fiction work The Political Doctrine of Sun Yat-Sen, as well as his book Psychological Warfare, which was used for many years as a text at West Point). Books signed by him are uncommon. Bought off eBay for $45.
