A silver cigarette case which once belonged to legendary motor racer Sir Malcolm Campbell is due to go under the hammer.
The souvenir, set to be sold at Gorringes auctioneers in Lewes, East Sussex, on September 8, is expected to fetch up to £3,000.
The case has on it signatures and doodles by Campbell's team of engineers and has the inscriptions: "If found, return to M Campbell, Chislehurst, Kent, Reward will be given."
It went into the possession of Mr Campbell's son and British speed record-breaker Donald Campbell when the former died at the age of 63.
As he was a non-smoker, Donald Campbell presented the case to Beryl Norris, a close friend and wife of his late chief engineer Lew Norris, in the 1960s.
It was Mr Norris who helped design the Bluebird boats and car in which Donald Campbell broke water and land speed records in post-war Britain.
Donald Campbell died while attempting to break his own water speed record in his jet-powered boat in 1967, at the age of 46.
