Well potted with a tall slender tapered body sweeping up to a round shoulder, surmounted by a short waisted neck and tapering mouth, the upper body freely carved with concentric rows of 'waves' pattern cut through the layer of black glaze to the white slip beneath, the countersunk base unglazed revealing the grayish stoneware, 13.9 inch high. Provenance: From a private Northern California estate by descent, acquired from L. Wanneick, Paris
