A great original piece here. This personalausweis was issued by the German Wehrmacht and granted the holder the right "to wear the stamped white armband with the red cross..."
In this case, the document holder was Ruth Steinmetz, a DRK Helferin. Listed on the document is her birthdate and location: April 14th, 1924 in Friedrichsfeld, Germany. This document was issued in on August 2nd, 1943. This would be an excellent piece to display with a German red cross armband, or in a WWII Red Cross collection.
