This is a small, ceramic shunga (erotic art) item that my father collected. It's unclear whether it's an ochoko (sake cup) or a small bowl (like for soy sauce), but it's a delicately made, refined, small piece of shunga. Would you like to add it to your collection? I believe it's in beautiful condition, with no scratches on the surface. Diameter: Approximately 6.5 centimeters
