This very unusual , Art Deco buckle appears to be made of celluloid. I do not know its provenance.
The gently curved buckle measures 4 and 7/16” (11.2cms) by 3 and 9/16” (9.1cms),
At top and base is an image of an imp of goblin with a grinning face and large ears. On the sides are red flowers and green leaves. The reverse is plain with some signs of age and use.
This lovely piece will arrive in a gift box.
