This dark red guilloche enamel butterfly pin has a black body and black eyes as well. Its wings are delicately scalloped and its antennae have a lovely curl to them. The workmanship is fine. The marks indicate that this pin was made after 1940. The marks include Andersen's scale mark, not seen on every piece. The metal is gold over sterling (vermeil). There is a secure C-catch, typical of Scandinavian pieces from the mid-twentieth century. This pin is in excellent original condition. It measures 3/4" X 1 1/4" and weighs 4.1 grams.
