As part of the John C. Campbell Folk School’s 100th anniversary celebrations, a long-hidden treasure of Appalachian history has been unveiled for a limited audience. A rare, hand-drawn map of the Southern Appalachian region created in the early 1900s by John C Campbell Folk School founder Olive Dame Campbell and researcher Elva M. Dickey was revealed to board members, staff and select media after being cleaned, preserved and stabilized.
