Kennkarte (Deutsches Reich) issued to a Reich's citizen. Because the ID card was temporarily used in postwar Germany, the swastika on the cover has been covered up.
This ID card was issued on 18 April 1940 and was valid until 18 April 1949. Unfortunately, the picture that came with this ID could not have been correct. The ID holder should be 18 years old, but the person in the photo is clearly not that young. Also, the holes in the picture where it was supposed to be fastened does not match holes in the ID. The picture is loose.
