Thank you for looking. This is a Bizen ware sake flask/single flower vase. Height approx. 12 cm, outer diameter of opening approx. 3.3 cm. This was obtained by my father, who was born and raised in Bizen City, from acquaintances, friends, and artists. He said that some of his collection were quite old or by famous artists, but now it's uncertain which ones are which, or if he was telling the truth. Please look at the images and make your own judgment and take responsibility regarding the value of the item. There is no original box or artist's booklet. There is a potter's mark, but I do not know the artist's name. This is a long-term, amateur storage item. We appreciate your understanding.
