A 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. This large warming dish is in very good condition with only slight wear to the outer border. Measuring 11 1/4″ x 16″. Also available to the buyer if they want it, as a bonus, ┬áis an appropriate cover for this piece, in sepia Fitzhugh, but bearing the monogram from one of the other Thomson services. Circa 1820.
