This is a stylish design by Susie Cooper for Wedgwood. The pattern is called Old Gold Keystone and it dates to the 1970s. It features a Greek Key design around the outer rim of each plate.
On offer here are a set of six side plates, as photographed.
Each plate is 6 3/4 inches in diameter and all are in excellent condition - with no chips, cracks or cutlery marks on the surface. The glaze is all nice and shiny.
