Sixteenth plate cased photographic portrait of an unidentified Civil War–era soldier, presented in a thermoplastic case with raised molded decoration. The image shows a bearded man in a dark military coat with standing collar and visible buttons, posed in a studio setting and framed by an oval gilt brass mat. The scale, presentation, and uniform style are consistent with mid-19th-century cased ambrotype portraiture from the Civil War period.

The thermoplastic case features a molded figural design on the cover and opens to a velvet-lined interior opposite the image. This type of case and mat combination was widely used during the 1850s and early 1860s, particularly for small-format portraits intended for personal keepsakes during wartime service.

No photographer’s imprint or identifying text is visible, and the sitter remains unidentified. The image is housed in its original period case with intact hinges and clasp, preserving the original presentation format typical of Civil War–era personal portrait photography.
