The Smithsonian’s new National Museum of African-American History and Culture is exhibiting a stone once used as a slave auction block in Hagerstown. We discuss slave auctions of enslaved and free blacks in western Maryland and the fissures still felt from those sales. Our guest is Mary Elliott, a museum specialist at the National Museum of African-American History and Culture. She helped research, conceptualize, and design the “Slavery and Freedom” exhibition at the museum, where the auction block is housed.
