Beautiful old postcard with picture of Wawel castle in Krakow with SS Polizei stamp. Wawel was the headquarters and central offices of the Generalgouvernement of the Gauleiter Hans Frank. On the reverse we can see an ink stamp of the Polizei Regiment in Krakau, that was inside the SS apparatus, and therefore post was sent via SS Feldpost. Probably from Battalion 101 stationed in Krakau . This postcard is circulated and dated 1941. Very good condition.
