Want to own a rock star's used underwear? A charity sell-off of Aerosmith singer Steven Tyler's possessions might be for you.

The big-lipped father of Liv Tyler is auctioning items including clothes and guitars in aid of MusiCares MAP Fund, which offers help to musicians recovering from addictions.

Described by Julien's Auctions as "a chance to own a piece of his singular style", highlights include vintage Aerosmith T-shirts, stylish suits, and, yes, even pre-worn boxer shorts (Est: $100 - $200).

There is also an enviable collection of guitars signed by the likes of U2, Paul McCartney, Metallica and David Lee Roth.

Tyler says: "So this is a personal gesture - a way for me to literally dive into my closet and give back…even my skivvies…are going up for auction in support of MusiCares."

This is the first time such an extensive collection has been donated by Steven Tyler from his personal wardrobe.

The sale by Julien's Auctions will take place at Hard Rock Cafe New York on 21 November.
