TRUE VINTAGE Gold & Hand Carved Boxer Dog Cufflinks

One of a kind! I have not come across any cufflinks like these. Signed by artist Robin Wood NYC. These belonged to my grandfather and are circa 1930-40s when he owned a Boxer. I believe them to be carved walnut and to be True Vintage. Please view photos for condition and measurements. In the last photo the four ears are visible; the one on the left is chipped at the tip of the ear. Gold plated posts are stamped 1/20-12KT G.P. Please know that the above description is what I believe to be true from family recollections and photos but these cufflinks have not been assessed professionally.
