Sydney: A cricket bat used by Australian great Donald Bradman and signed by his 1948 "Invincible" team is expected to fetch up to 20,000 Australian dollars (USD 17,900) at auction this month, an auctioneer said on Friday.
Charles Leski, whose company is selling the item, said Bradman used the Sykes bat to score 115 in his final first-class innings at home before the team travelled to England in 1948.
The Invincibles went on to become -- and remain -- the only Australian side to go through an entire Ashes tour unbeaten.
The item, which spent 20 years on display at the Western Australian Cricket Association (WACA) from 1984, will be auctioned on August 15 in Melbourne.
"Few items of cricketing memorabilia overshadow those belonging to Sir Donald Bradman," Leski said.
"Of these, his bats are among the most prized possessions because they were his ultimate stock in trade.
"Together with his baggy green caps, they represent his unique talent that has yet to be matched."
The legendary Australia batsman, who died aged 92 in 2001, played his last match in England in 1948 and retired with a yet-to-be-topped Test batting average of 99.94 despite scoring a duck in his final innings.
