This is a vintage blue lustre trim teapot with hand painted orange flowers and green leaves. There are also a pair of ducks or other waterfowl to the left of the flowers, which is an odd detail on this type of piece. It is marked Made in Japan on the base. The teapot is 5 1/2" tall to the top of the lid, and 8" long tip to handle. It is in excellent condition with no chips or cracks.
