This demitasse cup and saucer set was produced by Royal Worcester in England. It is unusual with an accordion type design on one side and a smooth surface on the opposite side. The set is ivory with gold trim. The footed cup is 2 1/4" high with a 2 3/4" diameter. The saucer has a 4 5/8 diameter.
There is a small chip on the inside of the cup visible in picture 11, otherwise in excellent condition. The maker's mark places the production of the set to be before 1862.
