Rare and unpublished early colour photos of The Beatles on tour are to be sold at auction.

They were taken on the band's triumphant summer 1964 tour of the US. The collection of 65 slides contain many stage shots.

Paul Fairweather, of Omega Auctions in Stockport, Cheshire, said: "We are expecting worldwide interest and estimate that they will achieve in the region of £10,000 to £15,000."
