Caption on verso: "Langley aeroplane. This aeroplane was designed and built by Professor Langley, assisted by Mr. Charles Manley, who designed the steam engine installed in this plane. The initial trial was made May 6, 1896, near Washington D.C. and fell into the Potomac river, but afterwards became a relic of the Smithsonian Institute. Later it was taken to Hammondsport, N. Y. where it made many successful flights. Lieut. E. Doherty, Aviator."
