Johnny Cash guitars, handwritten lyrics, stage outfits and other memorabilia will be auctioned on December 10.

Julien’s Auctions in Los Angeles is holding a three-day sale with over 1,000 lots available. The Daily Express reports that items include Cash’s famous blue jump suit, the guitar on which he wrote “I Walk the Line” and various handwritten lyrics. Other highlights include a pair of early stag pants made by Cash's mother, the jumpsuit Cash wore while rehearsing at San Quentin prison (and immortalized in the photograph now known simply as "The Finger") and knee-high boots with an elaborate eagle design on alligator leather.

The auction house expects some guitars to sell in the vicinity of $30,000, while lyrics are predicted to go in the $3,000 – $5,000 range.

A portion of the proceeds from the auction will go to MusiCares, a charity benefiting musicians in need.
