Football boots worn by Tommy Gemmell in Celtic's 1967 European Cup final win could fetch up to £10,000 when they are auctioned later this month.
The Adidas boots are being sold by an anonymous Glasgow businessman, whose father was friends with both Gemmell and fellow Lisbon Lion Bertie Auld.
The seller's father was with Gemmell, who scored the first goal in the final, after a training match in 1967 and jokingly asked if he could have a "token from Tam".
Gemmell is said to have tossed him the worn-out boots, saying: "I wore these in Lisbon, tell the wee fella to look after them."
Marked with the Celtic star's initials, the boots have been on display in the Scottish Football Museum at Hampden Park for the last nine years.
They are expected to draw international interest when they go under the hammer in the McTear's Sporting Medals and Trophies Auction in Glasgow on Friday, July 19.
An Adidas holdall from the famous cup win belonging to Auld will also feature in the auction, along with Jimmy Johnstone's match-worn jersey from the 1967 World Club Championship game against Racing Club.
The holdall could fetch £2,000 while the jersey is estimated at £3,000 to £5,000.
Brian Clements, from McTear's, said: "We have seen many important pieces of football memorabilia come through our doors over the years but rarely have we seen a piece with such huge historical significance.
"Any memorabilia associated with Celtic's momentous 1967 European Cup win is important but the boots that scored one of Celtic's two goals are on another level entirely.
"Although the seller has had the boots for over 50 years, he has decided the time is right to pass on the baton and let another Celtic fan get some enjoyment from this amazing piece of Celtic memorabilia.
"The Tommy Gemmell boots and Jinky Johnstone jersey are important pieces of world football heritage and not surprisingly, we are already seeing international interest in both items."
