The Original Slave Market

I found this picture of the original on Georgias Virtual Vault. It stated
"Louisville (Jefferson County), 1960-1970s. Slave market, built in 1758, was probably also used as an open-air market. Until 1796 when Jefferson County was created, this area was part of Burke County. [Photograph of slave market, Louisville, Jefferson County, Georgia, between 1960 and 1979] '
