This is another rare piece by Marcel BOUCHER from the 1940s. It is Sterling silver with a gold wash (vermeil). It is marked MB and Sterling. There is some mild wear to the gold wash. Mostly you see some tarnish. I am always conservative about doing a polish and clean on something the future owner may prefer otherwise.
The piece measures 2 1/2" by 2 1/4".
A treasure from my own collection!
