"Selection" of Hungarian Jews on the ramp at the death camp Auschwitz-II (Birkenau) in Poland during German occupation, May/June 1944. Jews were sent either to work or to the gas chamber. The photograph is part of the collection known as the Auschwitz Album. See Auschwitz Album, Yad Vashem: "The Auschwitz Album is the only surviving visual evidence of the process leading to mass murder at Auschwitz-Birkenau." The collection as a whole was first published as "The Auschwitz Album" in 1980 in the United States, Canada and elsewhere, by the Nazi-hunter Serge Klarsfeld, but individual images had been published before that – for example, during the 1947 Auschwitz trial in Poland and the 1963–1965 Frankfurt Auschwitz trials. It is not known when this particular image was first published.
