What is described as a "pristine" copy of The Beatles' "Sgt. Pepper's Lonely Hearts Club Band" album autographed by all four band members is up for auction.
A statement from Dallas-based Heritage Auctions says the bidding for the album has passed $110,000 and could surpass $150,000 by the time bidding is closed at March 30.
The Beatles signed the album jacket on the gatefold above the pictures of their heads. Heritage spokesman Noah Fleisher says the bidding started at $30,000.
