While last year, a handwritten letter by Paul McCartney auditioning for a new Beatles drummer fetched £35,000 at auction, this year a promotional poster of The Beatles has fetched £27,500 at auction. The poster was used to promote a show at Liverpool's Cavern Club , which took place on November 30, 1963.

London auction house Christies said that it was the earliest Beatles poster they had ever been offered, reports whatsellsbest.com. The poster had been reportedly hand-painted specifically for the lunchtime concert. The Christies listing read: "This is the only known copy of this poster. Posters from this period in the Beatles' history are exceptionally rare and only a handful of posters documenting their appearances at the Cavern Club are known to be in existence."

The Beatles performed their first lunchtime show at the Cavern Club on February 9, 1961. They are reported to have performed at the now legendary club 292 times before their last show there on August 3, 1963.

Last month, a rare picture of The Beatles walking 'backwards' across Abbey Road sold for £16,000. The photo, taken by late photographer Iain Macmillan, shows the band walking right to left across the zebra crossing outside the London studio where they made their 1969 album - the opposite direction to the photograph which appears on the album cover.
