Holocaust 1941 Ausweis issued to the coal supplier near Treblinka camp

One of the rarest of issued Ausweis that I have ever seen: Dating from November 1941 and used up to September of 1942, it was used at the small train station of Malkinia near the Treblinka death camp , about 4 km away. The holder was working for the GG main fuel supply corporation that was in charge of allocating fuel & coal to the trains and train stations of the Ostbahn, the railway system of the General Government. The holder was most likely aware of the transports reaching the camp and the trains going through his station, transports being sent from the Warsaw Ghetto in 1942.
