This undated image released by PBS shows, from left, Elyse Luray, contributor Dawn Peterson and Wes Cowan, from "History Detectives" with Bob Dylan's guitar. The electric guitar that Bob Dylan plugged in at the Newport Folk Festival in 1965 may be the most historic instrument in rock music, and it has sat mostly unnoticed in a New Jersey attic for most of the 47 years since. Dylan left it behind in an airplane and it was taken home by the pilot. The late pilot's daughter recently took it to PBS' "History Detectives," who authenticated the potentially fortune-making find in an episode that will air starting next Tuesday, July 17.
