NSDAP Gronau Grenzland Treffen 1937 Stick Pin-This pin commemorates a meeting that took place in the border district of Gronau. Gronau is located in the North Rhine-Westphalia area of Germany. The gathering brought together the districts of Gronau, Grenzland, and Treffen. The green and gold shield on the face represents the district shield. The green and gold finish on this pin is excellent. This shield sits on a mobile swastika that has the names of each Region plus the date of 1937 written on its arms. This pin measures 15mm square. The stick pin is knurled on this example. Just excellent.
