The Aeromarine 75 could seat about ten passengers and was a civil conversion of the American-built Felixstowe F.5L, itself based on a Curtiss design. Civil aviation in America lagged behind Europe through lack of government support, but Aeromarine's own airline was quite innovative, with branches in Florida and New York plus a Detroit - Cleveland service across Lake Erie. The Great Lakes Division only lasted from July 1922 until September 1923 though. In other photos its aircraft carry names and a light paint job. Here the rear fuselage reads 'Aerial Express' and a British contemporary source mentions the Aerial Express Company of Detroit. Photo from: Wayne State University
