This is an original 19th Century Fort Assiniboine, Montana U.S. Army Fort Photographer self portrait, L.S. Hazeltine. Fort Assiniboine is located in Northern Montana, near present-day Havre, Montana. The Fort was built in 1879 and operated through 1911 and included 10th Cavalry Buffalo Soldiers, made up of African-American soldiers. L. S. Hazeltine was the official photographer of the fort and would have taken photos of the soldiers and local Sioux, Nez Perce, Chippewa and Cree people. The fort was located within a massive military reservation stretching south to the Missouri River, north to the Milk River and containing the Bear's Paw Mountains. It encompassed 704,000 acres (1,100 sq. mi.) at its maximum extent in 1880. At its peak, it garrisoned more than 750 officers and enlisted men and their families. With 104 buildings, the fort was one of the largest ever built in the United States. Notable assigned personnel included the post-Civil War 10th Calvary Regiment, later known as the Buffalo Soldiers, a segregated African American US Army unit, and General "Blackjack" John Pershing, commander of the American Expeditionary Force in WWI. The fort was operated by the US Army until 1911. The carbint card is marked on the back, “L. S. Hazeltine Post Photographer, Fort Assinaboine, Montana” and on the front L. S. Hazeltine, Instantaneous Photographer.” It shows Hazeltine in his suit posing at one of his photography studio spots, standing atop what looks like a Buffalo Robe and boasting his rather large mustache. The outer edge is beveled with a gilt border. Good condition photograph, bright and reflective of the photographic processes used during that era, 6.5"L x 3.75"W. U6.
