Diving Dolphins, Sowerby

A very recognizable design with three dolphin feet and a floral exterior. The interior (as can be seen in the bowl on the right) is Sowerby's version of Scroll Embossed. The bowls are sometimes referred to as compotes. Rosebowls measure about six inches across and bowls spread to about eight inches.
