This unusual butterfly pin has very deep curvature, making it three-dimensional. Its marks identify Einer Modahl of Oslo, Norway as its maker. It has a tube hinge and C-catch, making it mid-century in age. The wide-spread wings are dark red with pretty veining in guilloche enamel. The body is white enamel, and the butterfly has tiny green enamel eyes. This pin measures 1" across, 7/8" high, and 3/8" deep. It is in excellent original condition.
