(Royal Crown Derby). ROYAL CROWN DERBY - LARGE WELL & TREE PLATTER - "KING'S PATTERN"/"DERBY JAPAN." 19 X 15 1/4 inches. Handpainted pattern in blue, orange and gold, with the Royal Crown Derby mark and the number "3590" on the base. Old when I bought it at an estate sale in the 1960s. In excellent condition - no scratches, glaze wear, etc., except with a small chip on the base, visible only when turned over. A superb example of a classic Royal Crown Derby pattern, monumental in size and appearance.
