Vintage Ceramic Hand-painted Pin/Brooch

Vintage Ceramic pin, circa 1980s, with an art deco look and feel. Painted on an abstract shape of cream colored ceramic topped with a clear glaze, the detail of the woman's face and clothing is a work of art. Just above the woman's hat is a small black mark, as shown in photo #1. On back in photo #2, some irregularities on the ceramic can be seen, as would be expected on a hand-made piece. Has a bar-pin clasp. 3"W x 1.75"H.
