A nine-year-old boy who won an award for litterpicking has found a Fanta bottle dating from the 1960s on a beach.
Theo Yeldham is a familiar sight in Hemsby combing the shoreline for litter and clearing up after summer crowds on the sands.
He was with his mum, Hannah Yeldham, on the beach on June 25 when he spotted a Fanta bottle poking out of the dunes.
The bottle had been buried in the cliffs for the last sixty years but has recently been uncovered by coastal erosion.

Ms Yeldham said: "The Fanta bottle was the first old thing Theo found. He was really proud he found something so old.
"The only way I could age it was to go online," she added.
Theo also found a Walkers crisp packet dating from 1997.
"For me it’s amazing they’re still in almost pristine condition. This proves that things don’t break down and decompose," Ms Yeldham said.
On that day, the mother and son duo hauled home half a bin bag's worth of mostly plastic rubbish - as well as a car tyre which Theo pushed all the way from the beach to their house.
"And that was only a quick litter pick as we had the dog with us. We can get double that when we have more time," Ms Yeldham said.
Previously, they have found crisp packets dating from the 70s and 80s.

Ms Yeldham, a seal warden, said that her son has seen seals entangled in plastic rings so has witnessed first-hand what happens when rubbish gets into the sea.
Theo has become a familiar figure on the beach near Great Yarmouth and he has his own blog page Jr Seal Ranger Theo documenting his rubbish finds.
Last year, he won a BBC Bitesize award for his efforts after being nominated by his teacher.
