This medal depicting the busts of King Albert and Queen Elisabeth of Belgium shows a likeness to that of one that was made by Godefroid Devreese, in Belgium in 1916. The back is dated 1910 along with La Bonte regne dans les cours. I believe this to be an ornamental copy.
With a hallmark on the chain of Germany this piece does have some age and exhibits a wonderful patina. The pendant measures 1-1/8'' in diameter and the chain is 18'' long. No flaws detected.
