Handpainted. Made by Marutomoware Japan. Measures 7" by 5.75" by 4". No chips or cracks. There is some normal age related crazing.
Cheese preservers were used in the days before refrigeration.
The domed covered lid has a small vent hole above a wing which keeps the cheese from drying out, sweating, molding and odor control. The hen rests on a small plate edged to simulate green grass.
