A piece of wall from the Ed Sullivan Show, which was signed by all four of The Beatles, is estimated to sell for £650,000 ($800,000) at auction.
Following their first American television appearance on the Ed Sullivan Show on 9 February, 1964, the famous four added their names to the set.
The large section of moveable wall, called a hard wall traveller, was used as the backdrop and appeared in front of 73m viewers.
The show sold out instantly, with over 50,000 requests for the mere 728 seats.
During the show, they performed five songs including All My Love, Till There Was You and She Loves You.
Asked by the stage hand, Jerry Gort, they were the first of many to sign the backdrop, adding smiley faces and the message “The Beatles were here”.
He claims that John, Paul and George signed the wall first, with Ringo having to be lifted by the waist to sign.
The wall comes with a letter from Jerry detailing the events of the signing and how the wall nearly met a grisly end, almost being sent to the dump.
It was instead saved and sent to a young fan, Loftin Sproles, who later sold it to Rodney Cary who displayed it over a bust of the Beatles.
In addition, a second letter from set designer Bill Bohnert is also included but the contents are not described.
Measuring 16 inches by 48 inches, it is professionally mounted in a display frame to protect it.
The auction is set to close on 23 September and is estimated to sell for between $750,000 ( £600,000) and $1 million (£800,000), with a starting bid of $500,000 (£400,000).
