This is from a collection that my family had. They're getting rid of it because they want other things. It's a sake cup (guinomi) by a potter, with Oribe glaze. It's a cylindrical guinomi, or sake cup, with iron-painted designs typical of Mino ware Oribe. The carefully hand-painted design is beautifully done. Is this from a Mino ware potter? The artist's name is unknown, but there is a mark on the back. Someone knowledgeable should be able to identify it! The size is approximately 6 cm in diameter and 7 cm in height. I bought it for everyday use, but I never used it, so I'm offering it to someone who likes it! Please check the condition carefully in the photos. If you have any questions about price negotiations or if you want to buy multiple items, please comment.
