Rubbish from the 1960s has washed up on Britain's beaches.
The litter, including Golden Wonder crisp packets dating back to 1967 and 1968 and a Revels packet from the 1980s, was collected by Surfers Against Sewage (SAS).
The campaigners have collected more than 25 tonnes of rubbish from UK beaches at 130 beach-clean events this spring, the BBC reports.
Photos of their retro finds were captured and have been released to raise awareness of sea pollution.
Andy Cummins of SAS said: "It raises the awareness of the problem of human litter in the seas.
"Most of the things we find are made of plastic and they are breaking down into smaller pieces.
"This becomes a plastic soup which is inadvertently eaten by marine life."
At Exmouth in March, 25 volunteers filled 34 rubbish bags in three hours.
"There were some huge items, including a discarded metal bin, stuck in Maer Rocks," SAS local organiser Ross Curwen told the Exmouth Journal.
"There were also a couple of bank anchors – the large metal stakes that boats use if there are no moorings – and fibreglass boat bits."
Last month, it was reported that an incredible 223,405 pieces of litter were collected by volunteers in the latest Marine Conservation Society Beachwatch Big Weekend, where local people hit the beach to pick up litter. This was the 20th year they had done the survey - and featured the largest quantity of litter ever seen by the volunteers.
They found a number of bizarre objects. Among the weirdest were half a TV, a French bullet-proof vest, a pack of bacon, a brass candlestick, some plastic bird feet, a birdcage, a bath plug, half a canoe and a set of dentures.
Their figures revealed that the worst offender was Holes Bay in Dorset, where 60 bags of rubbish were found. This was followed by Chesil Cove Shore in Dorset with 50 bags, and Gunwalloe Fishing Cove shore in Cornwall with 42.
