Modernist Hogan-Bolas Enameled Copper Pin Brooch

Modernist Blue Enamel on Copper Pin Brooch by Hogan-Bolas in very good condition. Mid century modern triangular enameled copper pin brooch. The front is enameled in blue, silver and turquoise and the back is copper with a functioning c-clasp pin. Measures 1.5” wide. In very good vintage condition (with minor patina on the back copper, which does not detract from the beauty of this vintage piece). Hogan-Bolas designers Robert Hogan and Deborah Bolas from Rhode Island are known for their modernist designs and ethereal enamel colors reflective of the Atlantic coastline.
