The photograph shows the Custer Battlefield marked with grave markers with a tiny ravine a unique and very desirable photograph from the Battlefield proper. The front of the boudoir card is marked as follows: No.7 Custer's Battlefield on Crow Agency, along the B. & M. R. R. Battle, fought June 25th, 1876. Custer and all his men were killed. Photographed and copyrighted by H.R. Locke, in 1895 Deadwood, S.D. On verso, an interesting printed advertisement for the Burlington Rail line, in part: "The New Short Line to Montana and the Pacific Northwest - Reaches every Health Resort and Mining Camp in the Black Hills. Passes within full view of Custer Battlefield..." Fort Custer was built near the Agency the same year. The Plains line of the B & M Railroad was built west along the Platte River from Kearney, Nebraska, during the 1880s. A northern spur route reached Sheridan, Wyoming, in 1893. During 1894-95 it was extended past Crow Agency to Billings, Montana, in the Yellowstone River valley. H. R. Locke was hired to make promotional photographs along the route. The back bears the “J.T. GILLMORE Deadwood, Sa. Dak.” stamp, which has been documented on several H.R. Locke images, including the images in this auction as well as images in the Yale University Library collection. This is believed to be James T. Gillmore (born August 4, 1841) who was the owner and manager of the Gillmore Hotel at Deadwood, South Dakota Territory as well as having holdings in the Montezuma and the Whizzer mines.
