The Beatles' first recording contract is set to provide one of the top lots at a Heritage Auctions sale.
The piece could make up to $150,000 when it crosses the block in New York on September 20.
Signed in Hamburg in 1961, it led to the release of the band's first single - My Bonnie.
The Beatles spent around two years in Hamburg. They performed at various venues in the city's notorious St Pauli district, where they developed a taste for leather jackets and amphetamines.
This was not strictly a Beatles record as they performed as the backing band for rock & roller Tony Sheridan. It was released under the moniker Tony Sheridan and the Beat Brothers.
It did, however, bring them to the attention of impresario Brian Epstein, who snapped them up on their return to Liverpool.
The lot displays all of the Beatles' signatures and is a key piece of their history.
Beatles memorabilia remains hugely popular among collectors. A signed copy of Love Me Do, the band's first proper single, is to auction on August 29.
