At a time when homosexuality was a criminal offence and harsh sentences were brought down upon gay men, these images of male affection from the 19th century are truly remarkable.
Embracing each other, holding hands and reclining together, these incredible black-and-white photographs provide a rare glimpse into men showing physical love to other men in the 1800s and early 1900s.

Although it is unknown whether the people in these unique photos were related, gay or just friends - the tender and close relationship between the men pictured is poignantly evident. For many, these images represent a small fragment of LGBT history that was repressed and concealed for so long.
