Likely a work by Living National Treasure, Akasui Ito. Oni-men (Demon Mask) Sake Cup, Mumyoi-yaki (pottery) Shudei (red clay) The gentle Okame (goddess of mirth) and the demon are in inverse proportion, making for an interesting piece. Okame has kanyu (crackling). There is some soiling. The box is also deteriorated. Will be carefully packed. Please read the profile before purchasing.
