I have a beautiful green and blue Vintage Murano Glass hand blown swan. It May have the makers initial? Which is either a w or an m depending on the angle. It's the only part of the swan that is done in a black or grey color. The piece is 12"from beak to tailfeather x 3" wide across body x 8 3/4 deep from top of head to flat bottom it sits on.
