A historically significant cartes de visite features Donald McKay, his wife Tuepum (Susan), and their daughter Minnie, captured by the photographer Wilkes of Baltimore. Donald McKay, a Warm Springs US Army Scout, played a crucial role during the Modoc War. His wife, Tuepum, was the daughter of the Warm Springs chief Simtustus. Their daughter Minnie gained fame as a renowned trick rider, often competing against grown riders in races and competitions.

Native American Donald McKay gained further renown by co-starring with Texas Jack Omohundro in Jack's Wild West show, which toured across the United States. Tuepum and Minnie occasionally joined them on stage, adding a familial touch to the performances. This image was likely taken during one of their shows in Baltimore, showcasing the McKay family's prominence in the Wild West show circuit.
