Beatles for sale again - this time it's a cache of photos showing the band meeting their Yellow Submarine characters in London's TVC Studios in 1967.
John, Paul, George and Ringo can be seen gadding about with cardboard cutouts of their characters in the studio where the animated film was made.
The pictures are expected to sell for more than £40,000 on Friday.
Some 65 pictures of The Beatles are included in the collection of 161 transparencies taken in late 1967 and early 1968.
