Vintage 1930's Celluloid Art Deco Pin of Dog with Swivel Head

This C-Clasp Pin measures 1.75 X 2.5 inches with a pin which the Head swivels on as can be seen from the back of the pin, The pin is very light and the pin is straight, both sides of this pin can be seen and have no signs of wear and tear or repair. This would be considered " A Rare Find " as it's almost an Antique and is in the same condition as when my Grandmother bought it. I don't know how much wear it has had, but my family cherrished and valued their assets, hoping to pass them on to their children and grandchildren. The Scottish Terrier is Cream and Brown with a Red Tongue. The Pin is not Stamped by any Designer.
