Pink Milk Glass Frog Covered Dish. This is a rare one because it will never be made again. This mold was designed by David Schepps who is a renowned Frog Collector and was made by Boyd Art Glass. It is marked SCHEPPS on the base. There is a Frog on the top and Frogs all around the base. The detail is wonderful on this Covered Dish. It is 5 1/2" and is in wonderful condition. These have been packed away ever since they were made.
