Rare photographs of the Beatles' first ever US concert, will go under the hammer in New York and the pictures of the young 'Fab Four' are expected to fetch around $ 100,000.
The black and white images will be auctioned at Christie's next month, reported Contactmusic.
The British band made their American TV debut on The Ed Sullivan Show in 1964 and played their first full live gig at Washington Coliseum in Washington DC two days later on 11 February.
The occasion was captured on camera by photographer Mike Mitchell and he is now selling a series of 50 silver prints, in addition to shots taken at the group's gig at the Baltimore Civic Center in Maryland.
The auction house's pop culture consultant, Simeon Lipman admits the pictures will be must-haves for die-hard Beatles fans.
"They're very close-up, very animated. The light is very interesting. They're very intimate shots," said Lipman.
