Chinese export porcelain rectangular deep vegetable dish decorated in underglaze blue with the traditional exotic houses, mountains, ships and a bridge set against a white porcelain ground. The central panel is surrounded by a "rain and cloud" border. The use of this earlier pattern border and the thick "orange peel" glaze indicate a date circa 1820. This style of dish is illustrated on page 245 (plate 656) of Nancy Schiffer's book "Chinese Export Porcelain." The deep dish measures 9 1/2"L x 8"W x 2 1/2"H. Very good overall condition. There is a barely noticeable original production flaw to the glaze in the interior and one thin chip in the glaze at the rim (see enlargements 10 & 11). There is no cover.
