Cabinet card portrait of Capt. W. A. Sligh, identified in period ink on the mount and reverse as a member of the South Carolina Penitentiary Guards in Columbia. The sitter is shown in three-quarter view wearing a double-breasted uniform coat with shoulder straps and metal buttons, suggesting a formal military-style guard uniform used at the penitentiary during the late nineteenth century. The reverse inscription reads “Capt. W. A. Sligh of S.C. Penitentiary Guards, Columbia, S.C., A.D. 1880.” The photographer’s ornate backmark identifies W. A. Reckling, Columbia, S.C., whose studio emblem is printed prominently in gold. Named portraits of penitentiary officers are uncommon and provide a visual record of prison administration during the Reconstruction and post-Reconstruction era in the American South. The clearly identified sitter and dated inscription add historical interest to this cabinet portrait.
