絵本椿説弓張月
This is a Japanese illustrated fiction book, an ehon picture book, drawn by the elderly Hokusai and published in Tokyo in 1888 by Hada Ken for a general readership. The pictures are black-and-white woodblock-style scenes of crowded outdoor action, mountain paths, and tiled-roof architecture, with dense hatching in foliage and rock that a designer could borrow for textured line work and dynamic crowd compositions.
