This 1966 photograph provided by the National Museum of American History shows two of Appalachia's most revered old-time musicians Tommy Jarrell with a fiddle and Fred Cockerham holding a banjo at Cockerham's home in Low Gap, N.C. The new Encyclopedia of Appalachia, which includes this image, challenges the notion that the region is still a place of hillbillies and poverty. (AP Photo/Courtesy of J.
