Rare calling card of the Civil War surgeon Reed Bontecou who was commissioned to run U.S. Harewood Hospital and Grounds in 1863 after serving in several theaters of combat medicine. Dr. Blair Rogers who has written a biographical essay on Bontecou, believes he is the first to make extensive use of clinical photography ("Reed B. Bontecou, M.D. - His Role in Civil War Surgery and Medical Photography" Aesthetic Plastic Surgery, 2000, Vol. 24, pp. 114-129). The many thousands of anatomical specimens and photographs he prepared made up the largest archive in the Army Medical Museum and were used extensively in the preparation of the Medical and Surgical History of the War of the Rebellion.

The reverse side of this calling card is a photograph of a composited photograph showing the campus of Harewood Hospital and Grounds. Quite possibly, it is an image that Bontecou himself made. Actual dimensions of the card are 62mm and 102mm.
