Striking photos are bringing museum visitors face to face with Victorian prison inmates.
The images have gone on display at Lincoln Castle for the first time and offer an insight into crime and punishment during the 1870s.
They were found in a document recording the lives and misdeeds of people who were held at the castle’s Victorian prison.
Among them were two Norwegian sailors, George Dahl, 24, and Harry Olsen, 22, who were sentenced to three months’ hard labour for burgling a house in Barrow upon Humber in June 1876.
The Register of Habitual Criminals was used by police to keep track of the previous convictions of people who reoffended.
Among the prisoners was John Holmes, aged 14, who was accused of stealing two pigeons and jailed for 21 days.
Another man, James Pringle, 21, from Grimsby, was given a month for stealing six tins of condensed milk.
The photos will be on display in the Magna Carta vault at the castle until February.
