1927 (Oct 23) Registered cover from Manyoni to the USA endorsed "Airmail Kisumu - Khartoum via Mwanza", with manuscript registration label of Manyoni, franked by Tanganyika 30c + 75c and U.S Air Mail 15c all cancelled in transit at Sigida, the U.S stamp further cancelled by blue crayon and again at Chicago with a duplex datestamp. Intended for the Gladstone Airways service but sent by surface mail via Daressalaam due to the crash of the "Pelican" on the 17th, which caused the air service to cease. U.S Air stamps were available in many foreign countries to pay for internal air mail within the USA. A scarce use of U.S Air stamps in Tanganyika, backstamped at Daressalaam, London, Chicago and Little Falls, fine. Photo on Page 50. (Image1)
