Geburtstag des Führers 20.4. - Heldengedenktag 15.3. Very interesting medallion from Germany, the 1942 German Calendar Medal for Degussa Industries, engraved by Prinz. This medal is particularly interesting in that it lists Hitler's birthday as the reference date for the calendar. Also Degussa Industries was huge in Chemicals, Metals, Energy and Real Estate, and supposedly in 1942 its subsidiary Degesch supposedly manufactured chemicals for the Third Reich including the infamous Zyklon B. The medal has grayed color and somewhat worn surfaces, but still very detailed engraving.
