This is a very decorative large dinner plate by Mason's Ironstone, Lane Delph, England in the Bamboo and Basket pattern, dating to the early 19th century, Georgian period, circa 1813-1820.
The plate is large, fairly deep and circular in shape with a notched rim.
It is decorated in one of Mason's boldly colored chinoiserie patterns, the Bamboo and Basket pattern, as documented on page 106 of:- A Guide to Mason's Patent Ironstone Patterns, circa 1813-1848, published by The Masons Collectors' club.
The pattern would have been transfer printed then hand painted in bold enamels, with a particularly colorful and distinctive border design.
The plate has the very early blue printed Crown and banner Mason's mark, dating it to the early 19th century, circa 1813-1820.
