The definitive reference book on Chamberlain’s Worcester Porcelain illustrates a covered cup and saucer in this style and says “The Chamberlain floral encrusted porcelains are scarce, if not rare, but examples of the 1824-40 period do exist.” These impressive vases are indeed rare survivors. There are some minor imperfections as is virtually always true with this delicate porcelain and one fine hairline almost imperceptible on the outside. The puce transfer printed mark gives the 155 New Bond Street, London address.
