The original recording of Elvis Presley's first radio hit has sold for €65,000 (£55,500) at a Dublin auction.
Rock and roll museums around the world, including the Graceland estate where the King lived, were expected to bid for the acetate that kick-started his career almost six decades ago. It went to an internet bidder.
Lot 62, a 1954 recording of That's All Right (Mama), was the highlight of the pop and rock memorabilia sale.
Ian Whyte, of Whyte & Sons Auctioneers said: "I am delighted, the sale went extremely well. There was huge interest. It is the first ever pop and rock sale in Ireland. I hope it won't be the last."
The 78rpm was recorded on July 5, 1954 by a young and unknown Presley, who had walked into the offices of Sun Records and the Memphis Recording Service in Memphis, Tennessee, owned by Sam Phillips.
It is the only known surviving promotional copy of his first commercial recording.
He sang a version of That's All Right (Mama) by Arthur Crudup which Philips recorded on an acetate record and sent to a local radio station DJ, who agreed to play it.
Mr Whyte said the station was inundated with phone calls and reportedly had to play it over 14 times during the course of the show.
