Very rare and rather uncommon ID factory pass issued in 1943 to a French worker from Nancy that was employed in IG Farben AG factory in Ludwigshafen am Rhein. ID card is laminated and in perfect condition. It reads: Werkausweis für Ausländer (ID pass for foreigners). It also has the red ink stamp for IG Farbenindustrie Lu (Ludwigshafen). IG Farben was a huge German chemical industrial network that was also known for having the big complex in Auschwitz III-Monowitz (Bunawerke).
