Rare photographs capturing The Beatles' record-breaking sell-out gig at Shea Stadium in New York are to hit the auction block later this month (Mar13).

Only two photographers were granted access to the stage area while the Fab Four were performing the 1965 concert - Robert Whitaker ran out of film during the show, so the majority of the images were snapped by amateur Marc Weinstein, who bluffed his way through security.

A collection of 61 of Weinstein's iconic images will now be auctioned for an estimated $22,560-$30,000 (£15,000-£20,000) at a sale in Stockport, England.

Karen Fairweather from Omega Auctions tells Britain's The Times newspaper, "We believe there are just nine surviving photos from the only other photographer backstage, so this collection is a unique depiction of a momentous occasion."

The auction will take place on 22 March (13) to coincide with the 50th anniversary of the release of the band's first album Please Please Me.

The Beatles' gig at Shea Stadium was the opening concert of the band's 1965 North American tour and broke records for audience attendance numbers.
