This is an adorable little Shawnee teapot!
It's from the Flower and Fern line, is a cheerful yellow color, and is marked USA.
Teapot and lid are in wonderful condition. The lid has light crazing (mostly on inside edge). Teapot has minimal exterior crazing and has interior crazing that has tea staining. It has a small 3/16" rough place on rim edge that in my opinion was probably caused by a lid bump. This rough place is difficult to see but you can feel it when you run a finger over the rim.
This is a beautiful piece that is not your everyday find!
