Grüne Woche Berlin 1939 Dog Show Charm

1939 Grüne Woche (Green Week) Berlin pendant for dog breeding. Not sure if this is for the (purebred) dog or his owner; it would look nice on either. Likely made up by a club from Kurmark for their members who attended the show. Grüne Woche is one of the world's largest fairs for food, agriculture and horticulture. The writing on the back translates to 'Breed dog show of the country - specialist group Kurmark' and is dated Nov 4/5 1939. It measures about 1' in diameter.
