Coro Feather Brooch Authentic Vintage Silvertone Pin

Beautiful Coro brand vintage brooch fashioned as a feather or leaf. Beautiful etched texture to this silvertone piece. Pinback works smoothly. Clearly marked or signed "Coro" as seen in photo. I'm unsure of the metal used here but it does not stick to a magnet, so I'm thinking aluminum. 3 1/2" impressive length, 1" in width. 88mm x 25mm. In very good used condition. Pegasus Coro logo!
