This is a nice item, the likes of which I've not seen. It's a dessert serving plate, complete with handle, for George VI and Elizabeth, 1937. Their image and the date is present, with the words, "Long May They Reign." The plate is trimmed in blue, and in perfect condition except for a small chigger bite on the underside of the plate which doesn't show on the front. The piece measures 8 and 1/4 inches in diameter.
