Vintage Industrial Brooch. Planchette hot Shaped. Three Inches Tall. Very Well Made. Aluminum, Brass, Resin and Stone. Three Inches Tall.
Appears to be circa 1980s, but unsure.
No signature found, but very well made by a competent artisan.
Wearable sculpture for sure.
Has expected surface wear to the metal, scratches, etc.
See photos at full size, as we try to show warts and all.
