The 1964 Fender Stratocaster Bob Dylan played at his very first electric show -- July 25th, 1965 at the Newport Folk Festival -- will be auctioned off by Christie's in New York on December 6th.

Dawn Peterson of New Jersey says the guitar has been in her family's possession for nearly 50 years -- after Dylan left it in her dad's plane. Dylan claimed he still owned the guitar after Dawn went public with the news last year on the PBS show History Detectives. She says a recently settled legal dispute with Dylan paves the way for her to sell it, along with handwritten lyrics that were in the guitar case.

The buyer will receive a bill of sale signed by the Petersons and Dylan (or his representatives). The guitar is expected to fetch between $300,000 and $500,000.

The lyrics include an early draft of “Absolutely Sweet Marie” (from Blonde on Blonde) and the Blonde on Blonde outtakes “Medicine Sunday,” “Jet Pilot” and “I Wanna Be Your Lover.” They are estimated to bring as much as $30,000.
