Infantry Pioneer or Color Sergeant Variant: Full-length standing studio portrait of a soldier sharply attired in a dark frock coat with light-colored piping and high-contrast collar trim. His sleeve bears a specialized insignia featuring an embroidered device positioned directly above his corporal chevrons, representing either a pioneer's crossed axes or an alternate regional variant of the color bearer's heraldry. He stands confidently with one hand tucked into his coat, next to a draped table. The reverse is blank besides research notations.
