A wonderful large brooch made up of a lovely layered early plastic material. This unique item is made up of two geometric ringed circles in a purple color with a layer of two forest green plastic ropes attached to each ring. The rings are attached at the back with an oval ring. The optic art looks amazing, the colors are unique and the design is very artsy! The pin measures 3 7/8" wide and just a little under 2" wide. This pin is in excellent vintage condition and would look amazing gracing any outfit or a hat! A wonderful geometric design that we will ship to you in a gift box. Thank you for looking!
