This handsome dinner plate is in the WASHINGTON VASE pattern in flow blue, not often found.  It was made by Podmore Walker & Co. between 1849-1859.  It is in excellent condition; no chips, cracks, restorations.  It is richly flown and has deep color.  The marks are both stamped and impressed.  Pearl Stoneware term was used by Podmore Walker on its china.  The plate measures 10 inches across.   Email me with any questions.   Domestic postage includes insurance.
