In 1975, photographer/filmmaker Bruce Jackson, who has spent decades documenting prison life, was visiting Arkansas’ Cummins Unit, a state prison farm. While there, he stumbled upon a drawer filled with old prison ID photos snapped between 1915 and 1940. Jackson recontextualized these as a unique form of portraiture in his book “Pictures from a Drawer.” Accidental Mysteries posted a collection of these striking images.
