This wonderful plate shaped as a clam shell is by Wedgwood. There is an impressed mark on the back with the company name. The characterization of early Wedgwood marks is a complicated issue and is handled in detail in Godden's book, Encyclopedia of British Pottery and Porcelain Marks, for example. Since the word "England" does not appear, we know that the plate is before 1891. There is a three letter code impressed on the back, the last character of which identifies the year of manufacture, which in this case would be 1871. The decoration on the plate consists of two insects, one butterfly, and three flower sprigs, with enamel accents. The wok is outstanding. There is a minor fleck on the back just on the edge of one of the extended rims. The plate is 8.5 inches across the longest way and a quarter inch less in the perpendicular direction (not quite a circle, in other words). The decoration with insects is most unusual, especially for this period, and the quality of the work marks the plate as being very special. I would also mention that there is on the back the number 7909 in gilt. Our research has shown that Wedgwood used a similar clam shell form for plates in graduated shades of pink. We have also found a few pieces of Wedgwood in a pattern called "Chelsea Sprigs" with very similar enameled insects and flower sprigs.
