An earring lost by late movie legend Marlene Dietrich more than 70 years ago at Blackpool Pleasure Beach is thought to have been found at the resort.
Dietrich became a US citizen and entertained Allied troops in WWII
Workmen found the pearl and gold earring while dredging a lake as part of construction work for a new ride.
"We have compared it to pictures taken at the time of her visit and it certainly looks like one of hers," said a resort spokeswoman.
The German-born star visited the site in 1934. She died in 1992, aged 90.
The actress and singer is thought to have lost the earring while on the park's new wooden rollercoaster, The Big Dipper.
She is said to have written to the amusement park later requesting a search for the item, which proved unsuccessful.
The resort spokeswoman said the earring "appears to have withstood the test of time quite well".
Also among the items found with the dredging of the lake were three sets of false teeth, a glass eye, wig and bra.
Tales of the star's visit have been passed down at the family-run park
"It has been a real eye-opener as to what people lose when they are having fun," the spokeswoman said.
Dietrich found international fame playing a cabaret singer in the 1930 German film The Blue Angel, and went on to become the highest-paid actress in Hollywood in the 1930s.
She was Oscar-nominated for her performance in Morocco (1930), while later successes included Shanghai Express, Destry Rides Again opposite James Stewart, Witness for the Prosecution and Judgment at Nuremberg.
