Aoi Art’s Comment:This masterpiece is a vibrant work attributed to Sekishu Sadatsuna, the son of Sekishu Naotsuna. The flamboyant hamon patterns likely influenced the evolution of the Shinto and Shinshinto eras, although the extension of these patterns is uniquely distinct. Highly recommended as a valuable and historically significant piece.
