James Dean has priciest autograph
James Dean's autograph is worth more than any other living or dead celebrity's, it has emerged.
The late Rebel Without A Cause star's signature can fetch as much as £18,000, according to a survey by memorabilia website Paul Fraser Collectibles.
The figure is well ahead of the runner up, Bruce Lee, whose autograph can still command an impressive £11,000.
When it comes to living stars, Sir Paul McCartney's signature can fetch £2,500 - up 25 per cent since last year.
But it trails behind Fidel Castro's autograph, which can make £3,750.
However, the firm said it's always worthwhile to invest in The Beatles' autographs.
"The Beatles are an evergreen investment - both individually and as a whole," they said.
"Each new generation falls in love with them and wants their memorabilia. They will always be the world's most famous band. Autographs of all the Fab Four on one page have grown by 8.7 per cent a year since 2000, and now stand at £9,500."
