WW2 kennkarte - special Jewish ID card from GG

Occupied territory under Germany, for the first 2 years, led to bureaucratic procedures of registration and paper work for all under their rule. For the first brief moment of occupation also the Jews were required to register and be issued identity documents. Today, we clearly understand that this documented system was essential in their next sinister plan: the extermination of European Jewry, and could be achieved swiftly and accurately only once all proper measures were put into place earlier.

Here is an example of a Jewish ID card issued at Lublin for a forced-laborer, a Jewish man, who was by then placed at the camps of Trawniki, the notorious location where eastern European SS men were trained and placed later on, some, as guards in the various extermination and concentration camps erected by the Germans. Post war testimony indicates that the ID holder here named Jojna was murdered on November of 1943, in Operation Harvest, were in just over one day close to 43,0000 Jews were shot into pits.

The residential section of the ID card, right side, was torn off, clearly no need to register, once being placed into a camp. How the document survived and located by his son after the war is still a mystery, he left Poland in 1948 for Israel with the only remaining item that belonged to his father, issued 5 years earlier...

I would be very interested for locating additional interesting ID's or Ausweis from the war for my collection.
