excellent condition a NSDAP German Reichsparteitag 1938 plaque. Very rare! Size 43mm Frontside: Two men holding the NSDAP flag and broken chain on an elevation under the eagle with swastika. Around the figures the date 1938 and Reichsparteitag. Backside: no markings. This is normal with plaques to be unmarked. The badges however are marked.
