Newly found photos shot by Paul McCartney at the peak of Beatlemania will shine at London's Gagosian Gallery until October 4. The shots track the band's swift climb from club gigs to global fame in 1963 and 1964. At Rearview Mirror: Liverpool-London-Paris, visitors can see candid shots McCartney caught with his 35 mm Pentax camera across six cities. These rare snapshots freeze time during the band's big break. McCartney caught their wild Christmas Show run and three weeks at the Olympia in Paris.
