Image Missing: Hearst Museum object titled Netsuke, accession number 9-7509, described as Kai-Riu-O, or Riujin-- netsuke in ivory, of a very old man with the sharp features and pendant hair of a witch-- a dragon crest-- who carries in his hand the tide-ruling gems. Note the intaglio cutting of this netsuke, the type much esteemed by the Japanese, which they dub "sharp."
