The last document signed by all four members of the Beatles is to cross the block at RR Auction.
It relates to the sale of 3 Savile Row, the former headquarters of their Apple label, and dates to November 8, 1980.
The Beatles set up the label in 1968, just as the band was beginning to fall apart.
The address was the location of their final performance in 1969. They played a concert on the roof before going their separate ways.
Apple Studios stayed open until 1975 before closing down. The band sold the building five years later.
Exactly a month after this document was signed John Lennon was shot dead outside his apartment in New York.
Beatles expert Frank Caiazzo told the Liverpool Echo: "This document was formally adopted in late November of 1980, thus making it one of the last documents signed by John Lennon during his life.
"John Lennon signed in black felt tip pen, and has added a facial caricature, Paul McCartney, George Harrison and Ringo Starr (who has signed as R. Starkey, his legal name as required on documents), have all signed in blue ballpoint."
It's valued in excess of $80,000 ahead of the sale's May 19 close date.
We have this cover of the Beatles' Hard Day's Night signed by the whole band for sale.
