A bat brandished by Don Bradman on his way to a double century is expected to fetch up to A$120,000 ($129,687) at auction.
The bat - signed by Bradman - was used on his first overseas tour with the Australian team, in a test match at The Oval in Londonin 1930.
It is the first time this piece of sporting history has been offered for sale.
The bat, which has been in the same family for 75 years, also features the signatures of 24 Australian and West Indian cricketers of the time, among them Bill Woodfull, Stan McCabe and George Headley.
