large and impressive Chinese export porcelain oval warming dish, finely hand-painted in the sepia Fitzhugh pattern and bearing a central roundel with the initials RRT for Richard Renshaw Thomson (1799-1824). Thomson was the son of a prominent Philadelphia China trader, Edward Thomson, serving as an agent on his father’s behalf, as well as American consul in Canton. Several services for this family exist and they are discussed in Philadelphia and the China Trade, pages 152-153. Accompanying this fine dish is a cover from one of those other services bearing the initials of a Richard’s brother, John Renshaw Thomson, who also served in Canton as consul, appointed by President Monroe. Both pieces are in very good condition with only slight wear. Measuring 11 1/4″ x 16″.
