Timothy O'Sullivan / Alexander Gardner albumen view of the quarters of Captain Harry Clinton, Quartermaster/Provost Guard, at the Army of the Potomac Headquarters, Brandy Station, Virginia, Dec. 1863-1864. The battle of Brandy Station, fought June 9, 1863, was the largest predominantly Cavalry engagement of the Civil War (and the largest to ever take place on American soil). It marked the end of the Confederate cavalry's dominance in the East. That winter, Brandy Station became the primary supply depot for the Army of the Potomac. Photograph – 6 1/8" H x 6 1/2" W. Matted and framed under glass in a stained oak frame, 10 3/4" square. Note: card taped en verso of mat states this is an original unmounted photo of a Civil War scene near Atlanta (location is incorrect) which was purchased from Alexander Autographs Auctioneers "years ago" and authenticated by Larry Gottheim; we have not confirmed this information. Provenance: the estate of Raeanne Rubenstein, Nashville, Tennessee. A graduate of the University of Pennsylvania's Annenberg School of Communication, Ms. Rubenstein was a professional photographer specializing in images of celebrities ranging from John Lennon, Janis Joplin and Andy Warhol to Johnny Cash and Dolly Parton. Her work appeared in Rolling Stone, Life, People, and most recently the Ken Burns documentary, Country Music. CONDITION: Photograph in good condition with light toning, particularly at edges. Some light staining en verso with likely later pencil inscriptions, "326 Gardner"and "Atlanta" and "IX".
