This is a wonderful white antique serving platter by Hanley of England. It is in wonderful condition for its age and I have shown the marking on the back. There is another mark indented into the china. It is 16 1/2 inches wide and 12 inches long. The platter is white.
The mark 7G was in pen, and is NOT part of the plate markings, I only included this picture as it is clearer.
