This colorful midcentury pin features a piece of enamel glass set in a frame of sterling silver. The enamel features a central design of three lavender amorphous forms outlined in silver wire, as with cloisonné, on a mottle blue and green background. The back of the pin bears a mark for sterling, as well as the maker’s mark of Holbrow.(This could be the mark of Florence G. Holbrow, of South Lincoln, MA. Her work appeared in a 1963 competition and exhibition of modern jewelry held at the Everhart Museum in Scranton, PA.) There is a rollover clasp in good working order. The pin measures 1 ½ inches long by 1 ¼ inches wide.
