1970s Napier Brutalist Goldtone Modern Square Burst Pin Brooch. Inverted pinpoints of shiny gold tiny balls make this brutalist design square pin sparkle without stonework! A cavernous square center open is lined with this brutalist pinpoint frame and shines brightly. 3" wide by 2" tall. The pin is signed and in excellent vintage condition. Many in the era would use openwork pins like these to temporarily store sunglasses or reading glasses casually and comfortably close! Elegant-ladylike and MODERN!
