A Chinese export porcelain tea bowl and saucer made for the American market, specifically for the New York market as it from a service bearing the Arms of the State of New York.  Patriotically-themed services such as this were ordered in the early years of the Republic as a show of pride and loyalty to either specific states or our fledgling nation.  The saucer measuring 5 1/2″ in diameter and with three hairlines; the tea bowl 3 1/2″ in diameter and in good condition with only some enamel wear.  Circa 1790-1800. $375.00
