Sonderkommando photographs
The Sonderkommando photographs are four blurry pictures, taken secretly on 4 August 1944 inside the Auschwitz concentration camp during World War II.  The photographs were taken by a prisoner in Auschwitz II-Birkenau.  This was Auschwitz's extermination camp - a place where people were sent to be killed in gas chambers.  These are some of the only known photos that show what happened around the gas chambers.
