FREDERICK, Md. (AP) -- A Frederick museum is exhibiting a slave sale document signed by Maryland's first governor, Thomas Johnson.
The Frederick News-Post (http://bit.ly/1e1qRCc ) reports that the document will be shown Wednesday night at the Delaplaine Visual Arts Education Center.
The exhibit is part of the annual meeting of the local African American Resources, Cultural and Heritage Society.
Organizer David Key says the document is among several slave sale records borrowed from the collection of the late Kathleen Snowden of New Market.
