A woman was stunned to find a 4p crisp packet from the 1970s in her garden.
Janet Midwinter came across the 50-year-old plastic wrapper in Sennen, Cornwall.
The packet is priced at 4p and carries the Crispi Crisps logo.
And she says it’s a warning to future generations.

“I was coming back from a dog walk and saw the crisp packet by my garden gate,” Ms Midwinter said.
“I usually pick bits and pieces up and put them in the rubbish.
“But I thought, ‘That’s an old crisp packet’.
“It’s a little ragged around the edges, but if one crisp packet can last that long, what are we doing to the planet?”
She believes the packet is around 53 years old and has now framed it.
She intends to put it next to a recycling point at Sennen Market as a warning to people about how long a plastic crisp packet takes to break down.
She said: “It’s just so people can see it and realise how a crisp packet can be in the ground for 53 years.
“It’s unbelievable that it is so old.
“Let’s try and get rid of the plastic.
“Just try and recycle as much as we can and try not to buy too much plastic.”
Manufacturers, Meredith and Drew sold Crispi Crisps from the 1960s until the 1990s.
The company was later taken over by United Biscuits which also owned KP Snacks, as reported by What’s The Jam.
Emily Stevenson, from the environmental group, Beach Guardian, said: “There is a sad, dark tale behind these finds.
“These plastic packets have been in the environment for decades.
“How much longer would they have remained had we not found them?”
