Votive Mirror with Eleven-Headed Kannon

Round, flat, circular object made of metal, likely bronze or copper, with a dark brown and gray patina. The object has a smooth, slightly concave surface with a darker center and lighter edges. Two small holes are visible at the top, positioned symmetrically on either side, likely used for hanging. The surface features intricate, etched designs and a central figure of a female deity with multiple heads, specifically eleven, which is a characteristic representation of Kannon. The background of the image is a plain gray color.
