The photographs show the inhabitants of Oświęcim - both Christians and Jews - digging ditches, probably anti-aircraft. The donor mentions that these were anti-tank ditches, but the analysis of the photographs does not confirm such a thesis. The event took place at the turn of July and August 1939. The photos were made available in 1985 in the Archives of the Auschwitz-Birkenau Museum in Oświęcim by Stanisław Neumann, an inhabitant of Oświęcim. (Description: Artur Szyndler, CC BY-SA 4.0)
