A copy of the Beatles' first single, 'Love Me Do' backed by 'P.S. I Love You,' signed by all four members of the group recently sold on eBay for $13,350 after 35 bids. 

The 1962 single features signatures from George Harrison, John Lennon, Paul McCartney and Ringo Starr, all scrawled in dark blue ballpoint pen. Lennon included three 'X' marks below his name; Harrison signed his first and last names on both sides of the hole that marks the center of the record.

The single's seller, Perry Cox, called the item "one of the most historic signed records there is," noting that it was autographed on Oct. 6, 1962, at Dawson's Music Shop in Widnes, England, just a day after the Parlophone 45 was issued in the U.K. Cox is the author or co-author of various books and price guides about Beatles memorabilia.

'Love Me Do' reached No. 17 in England in 1962. Two years later, it was released in the U.S, where it hit No. 1, riding a wave of Beatlemania.
