Rare Vintage Peacock Brooch Pin Green Dark Blue Enamel 1.5”

In vintage preowned condition. What is shipped is what is pictured. Check out all photos and zoom in. Unsigned from what I can see. In the listing there is a photo zoomed it where there may be a signature but it also looked like it could just be a zig zag. Pin works. Metal unknown. Looks to be enamel on metal. Looks like to the bottom left facing there are 2 spots missing enamel. Offers welcome. #classy # Gold Toned #Mid century #hat pin #scarf pin #accessory
