Written during her travels during the fall of 1941, this is a letter from aviatrix Laura Ingalls to her "friend" Sylvia Comfort. Ms. Comfort would later turn out to be key to the investigation of Ms. Ingalls as a German spy, as she was an infiltrator, documenting Ms. Ingall's subversive ideas and activities. The letter is typewritten, and on the stationery of the Murray Hill Hotel on New York's Park Avenue. It is signed "Ellen" because that is the code name used by Ingalls when she travelled. 9.25 x 6 in.
