Gorgeous brilliant blue plate, a full 12" in diameter, with bird and floral cloisonne artwork. The border has an insect bee or fly? alternating with a flower in a diamond design. Absolutely beautiful craftsmanship. The enamel on the back is worked around bronze swirls. There is a small 1/2" high foot that gives the plate a perfect raised effect when used flat as a centerpiece or buffet item. The plate does have a concave shape. Age is 19th Century but unsure of ...exact age, according to history of similar items. This was an estate purchase this past year. I will very carefully package and ship with just one day processing M-F. Any delays in shipping is that of the shipping agent and beyond my control. Insured shipping only.
