Marcel Boucher gold knot brooch late 50s signed 8098P

Beautiful vintage Boucher knot brooch, post-1955, number 8098P. All marks indicate this is a design that is post-1955, likely late 50s, possibly early 60s. Beautiful condition. Pin holds fast. No fading, no tarnish, no signs of wear that I can see. 1-3/4 inches in diameter. Legendary luxury jewelry designer of that era! Likely gold-plated, not a solid gold piece. This piece is a classic example of his complex, midcentury, open, 3-dimensional design, with rope elements as well as a brushed, textured ribbon accent. It's a stunner!
