Rare photographs of The Beatles' first ever concert in the U.S. are expected to fetch a total of $100,000 (£62,500) in July (11) when they are auctioned off in New York.
The Fab Four made their American TV debut on The Ed Sullivan Show in 1964 and played their first full live gig at Washington Coliseum in Washington, D.C. two days later on 11 February (64).
The momentous occasion was captured on camera by photographer Mike Mitchell and he is now selling a series of 50 silver gelatimn prints from his negatives, in addition to shots taken at the group's gig at the Baltimore Civic Center in Maryland on 13 September,1964.
The black and white images will go under the hammer at Christie's on 20 July (11) and the auction house's pop culture consultant, Simeon Lipman admits the pictures will be must-haves for die-hard Beatles fans.
Lipman says, "They're very close-up, very animated. The light is very interesting. They're very intimate shots."
