Vintage Art Deco Brooch Pin

Vintage Art Deco Brooch Pin. Could possibly be Pierre Bex or Catherine Popesco? This pin is unsigned but is quality crafted. Pin is integrated into the design and not attached. Vibrant yellow with contrasting red and black. In great condition for age. See photos Note: Most of my jewelry is pre-loved. I only wipe down jewelry. I do not deep clean any jewelry before shipping. I am not a professional and do not want to risk damaging any vintage item. I will note any flaws/defects. Please see all photos.
