This is a very large lovely platter in excellent condition. The platter measures 17 1/2" x 14" and is heavy ironstone. The English back mark is the crown of Ashworth Bros. 20th century version. This is an outstanding serving platter with its gorgeous 1 1/2" cobalt blue and gold border! Around the center is a delicate gold x design. If you have been wanting a large serving platter, this one is very nice!
