Cabinet card photograph showing a mounted man posed before the Northern Pacific Railroad photographic studio car of F. Jay Haynes, by Haynes of Fargo, Dakota Territory, circa 1885–1895. The railcar roof is lettered HAYNES, and the side panel reads F. Jay Haynes Photographer Northern Pacific, identifying the traveling photographic studio used by Haynes in his work as official photographer to the Northern Pacific Railroad.

Frank Jay Haynes (1853–1921) was the official photographer of the Northern Pacific Railroad and one of the most important photographic documentarians of western expansion. In 1885 Haynes purchased a Pullman railroad car and converted it into a mobile photographic studio and darkroom which traveled throughout the Northern Pacific system producing portraits and railroad views. The photographic car served as both studio and headquarters while Haynes documented the railroad and communities along its routes from the Dakotas to the Pacific Northwest.

The image shows the photographic car in a rail yard setting with water tower visible at left and full exterior lettering intact. Haynes cabinet imprint printed vertically at left: Haynes, Fargo D.T.
