Product Name: Rice Bowl Material: Ceramic Size: Outer diameter approx. 14cm, height approx. 7cm This item was obtained by my father, who loved pottery and tea, from acquaintances, friends, and artists. He used to say that his collection included some very old pieces and works by famous artists, but now it's impossible to tell which ones are, or even if it's true. There are no original boxes or artist's cards. There are potter's marks, but I don't know the artists' names.
