German politician and diplomat (1879–1969) who served as an Axis spymaster in the U.S. during World War I and later served as Chancellor (1932) and Vice-Chancellor (1933–34) of the German Reich. Tried at Nuremberg, he was acquitted and later wrote a number of books. ALS signed “Papen,” four pages on two adjoining sheets, 6 x 7.5, North Coast Limited letterhead, September 14 [circa 1914]. Papen writes to American friends while traveling through North Dakota. In part: “How strange is America!… The only excitement this morning was—the Billing [sic] Journal. It must be somewhat friendly against the Central Powers because I read with interest, that my participation in D’s … plot has as yet not been fully established. So I felt very comfortable taking my breakfast and had a vague idea, that heretofore I had certainly overestimated the celebrated U.S. Secret Service, who is watching me now a good full year….” Papen then goes on to discuss various political and personal matters. Removably presented on a collector’s sheet with historical information. Edge separations at folds (touching a few words) and light scattered soiling and handling wear, otherwise fine condition.
