A shallow 9" dinner plate from the White House Service of President and Mrs. James K.Polk. On the reverse is an orange printed mark of Edward Honoré, meant to simulate an invoice from his Paris firm. Circa 1846. At the top is the first use on china of the Presidential seal and the motto, “E. Pluribus Unum” in a ribbon across a shield. It is also the first time the colors of red, white, and blue appeared in a motif on the President’s china.
