Thank you for viewing. This is a Bizen-yaki sake cup (guinomi/ochoko). My father, who was born and raised in Bizen City, obtained these from acquaintances, friends, and artists. He said that his collection included some very old pieces and works by famous artists, but now it's uncertain which ones are, or even if it's true. Please view the images and make your own judgment and take responsibility for whether the items for sale are valuable. There are no accompanying boxes or artist's pamphlets. There are potter's marks, but I don't know the artists' names. These items have been stored by a private individual for a long time. Thank you for your understanding.
