An original WWII German General Government Kennkarte (identity card). This German/Polish bilingual document was issued citizens in occupied Poland. It is complete with original portrait, and is nicely stamped in several locations. See photos. 
 
The General Government, formally the General Governorate for the Occupied Polish Region, was a German zone of occupation established after the invasion of Poland by Nazi Germany, Slovakia and the Soviet Union in 1939 at the onset of World War II. The newly occupied Second Polish Republic was split into three zones: the General Government in its centre, Polish areas annexed by Nazi Germany in the west, and Polish areas annexed by the Soviet Union in the east.
