山水画譜
A Japanese ehon picture book of landscape painting called Sansui gafu, illustrated by Asai Ōsui and published in 1879 by Sanmidō, presumably for artists and students learning the brush manner. Its woodblock prints show mountains, trees, rocky shorelines, boats, and pavilions in ink line with sparse grey wash, and a designer could take from them the economy of linework, the layering of distant ridges, and the use of empty water and mist as negative space.
