This was called a River Stone Vase by Takaezu. The Vase is in excellent condition. Marked on the bottom with opposed TT markings. The vase has a rattle. It measures 11" in diameter and 4" high. This form was one of if not the last new forms that Toshiko developed. Uncommon as they were not long in Production. These are also referred to as PILLOW vases, see the RAGOARTS.COM catalogue.
