Vintage Artisan Americana Botanical Round Brooch Pin Pink Cypripedium Heart

I remember in the 1960s there was a resurgence of this ceramic craft where the Copper is painted with glass and then fired in a kiln creating this beautiful glazed piece. This could be earlier. The detail is fine. Little heart visible in the center! Sweet approx 1 1/2 “ Diameter. Wonderful Horticultural Botanical Eco Nature Loving Old Fashioned Gift. Probably from Maine.
