Full-length standing studio portrait of a soldier wearing a standard four-button fatigue blouse, featuring a highly distinct, large embroidered horseshoe emblem sewn onto his upper sleeve. He rests his hand on an upholstered parlor chair, posed against a neutral studio backdrop. The reverse features an expansive period pencil inscription identifying him as "Capt Saml Clark / of Newcastle Me. / Company E Second Reg Cav." Clark enrolled in Company E of the 2nd Maine Cavalry in late 1863, serving as a specialized company farrier and blacksmith managing vital horse-mobility logistics during deep raiding campaigns across Florida and Alabama.
