Sir Paul McCartney: 'Unearthing Beatles photos made me emotional'
Sir Paul took the images during "an intense three-month period of travel" in 1963 and 1964 but believed they had been lost.
He said unearthing them had "plunged" him "right back" into the experience.
The photos will be shown at the National Portrait Gallery as part of its relaunch and published in a book.
Paul McCartney Photographs 1963-64: Eyes of the Storm will run between 28 June and 1 October as one of two major exhibitions that will launch the London gallery's summer programme.
The images document December 1963 to February 1964, a period which was an important one for the Liverpool band, taking in their meteoric rise to global superstardom, their record-breaking appearance on The Ed Sullivan Show and the four-piece's youngest member George Harrison's 21st birthday.
