A litter picker has found a Golden Wonder crisp packet in the River Clyde, dating back to the 1960s.
The crisps were from pre-decimal currency and the weight was marked in 'drams' - with the packet labelling an offer expiration date on April 30 1969, two years before decimalisation was introduced in the UK.
Zoe Weir, who goes litter picking with her dog, Mackie, made the unique discovery and said it was the oldest plastic she had ever found.
