This is a nice 14 1/2" x 11" Blue Willow Platter in the traditional Blue Willow pattern on an earthenware body. The antique 1800's mark of a bird and banner is probably Podmore, Walker & Co.Turnstall Staffordshire, England circa 1834-1859. There is also an impressed clover shape mark on the backside. The color is medium blue. There is an under the rim chip ( about 5:00 O'clock ) on the right bottom. The surface has two small glaze pops and light crazing. All in all, it is in very good condition for its age.
