This Civil War-period photo depicts the extant Price-Birch (formerly Franklin-Armfield) slave pen at 1315 Duke Street, the northern headquarters and holding pen for one of the largest firms selling ‘surplus’ slaves from the Upper South to the Mississippi valley. The owners of the properties, J. Peter Dunston, Betty Dunston and Carey Mueshaw, supported the excavation by Engineering-Science of the structure’s basement and side yards in 1987.
