This bowl is 10 1/2 inches across. The signature is RS Prussia with a wreath but not easy to read. The bowl has beautiful roses and gold trim. The bowl has many pointed areas and is a white porcelain. This is one of the pretty bowls from the Germanic area known until the end of WWI as Prussia. These are well know porcelain bowls and are the cream of the crop. This bowl is perfect a small amount of gold is worn on the points but other wise perfect. A perfect treasure from Kansas.
