Dr. Bandwell, identified by period inscription on the reverse, is portrayed in this albumen carte-de-visite dating to the Civil War era. The vignette format, with the image fading to bare mount at the edges, was a popular studio convention of the 1860s, and the plain cream board with simple ruled border is consistent with that decade. No photographer's imprint appears on the reverse.

The portrait captures a bearded man with full, wavy dark hair worn past the ears and a thick beard covering the jaw and chin. His gaze is direct and composed, and the tight vignette crops the image just below the collar, leaving clothing largely obscured. The albumen print has faded to warm sepia tones across the entire surface.

The 6th Iowa Cavalry was organized in 1863 and served extensively in Missouri, Kansas, and the Dakota Territory, participating in campaigns against Confederate guerrillas and later in frontier operations. A regimental physician or surgeon attached to such a unit would have operated under demanding field conditions throughout the war's later years.

The reverse bears a period pencil inscription reading "Dr Bandwell," a partially legible town name, "6th," and "Iowa Cav."
