Union general and onetime commander of the Army of the Potomac (1824–1881); the distinctive whiskers he sported gave rise to the word “sideburns.” Carte-de-visite photo of Burnside posing in his dress uniform and sword, slightly trimmed in size to 2.25 x 3.75, signed in ink in the light portion at bottom “A. E. Burnside, Brig. Genl.” Trimming as noted and a hint of mild soiling, otherwise fine condition. R&R COA.
