Alec Baldwin - Alec Baldwin Auctioning Off Autographed 30 Rock Wall

Alec Baldwin is offering one lucky 30 Rock fan the chance to own a piece of Tv history from the set of the hit sitcom - he's auctioning off his autographed dressing room wall.

Filming on the Tv show's seventh and final season wrapped in New York in December (12), and the actor is taking part of the backstage area with him to auction off for charity.

The winner of the unique lot will also get to meet Baldwin backstage at his new Broadway play Orphans.

The actor states, "Nearly all of 30 Rock's remarkable gallery of well-known guest stars autographed my dressing room wall. That piece of wall can be yours, literally, and your gift will support two of my favorite charities."

Tom Hanks, Julianne Moore, Salma Hayek, Jon Hamm, Steve Martin and Cyndi Lauper are among the famous signatures scribbled on the wall.

But the CharityBuzz.com prize package doesn't come cheap - it's valued at an estimated $1,000 (£625) and has already racked up bids of more than $3,350 (£2,094).

The sale ends on 28 February (13) and all proceeds will benefit the Broadway Cares/Equity Fights Aids and the Children's Tumor Foundation.

The 30 Rock grand finale airs in the U.S. on Thursday (31Jan13).
