These graphite drawings were done from prisoner identity photographs. The photographs were taken by the authorities at Auschwitz concentration camp in Poland, Lubyanka Secret Police headquaters in Moscow and Tuol Sleng prison in Phnom Penh, Cambodia. 

These prisoners had almost everything taken from them; their homes, their families, their possessions, their names, their hair, their lives. In some cases this thin photograph appears to be all that remains as evidence of a person's existence.
