These female twin calves were born at Braunston, Rutland, around 1900. They were delivered by Justus Littler, an Oakham vet, but lived only a few hours after birth.
Mr Littler preserved them and they were displayed in a glass case for many years in the Littler veterinary practice at Elgin Lodge, Melton.
The calves, known as the two-headed calf, became famous in Melton. During both world wars they were regularly displayed in peep-shows in the cattle market to raise money for the Red Cross and other charities.
In the late 1970s the veterinary practice closed down and the calves were presented to Melton Carnegie Museum in 1981.
