Nice Arbeitsbüch (work booklet) that belonged to worker in Auschwtiz III Monowitz Buna werke IG Farbenindustrie plant in Poland for a period of time apart from other places in Germany. There are entries of all the places they worked for and the stamp of IG Farben Auschwitz Werke is perfectly visible. This plant was located in the area of Monowitz (Poland) and it was part of the vast complex of sub-camps of KL Auschwitz. Thousands of slaves were used to work in this plant during the existence of the camp and many were Jews, so the connection with the Holocaust is obvious. Great condition. Very interesting!
