Kōchō gafu
Kōchō gafu is a Japanese woodblock-printed sketchbook by Ueda Kōchō, published in 1834 and held by the Smithsonian Libraries. Its pages are open, unbordered-to-bordered line drawings of people, deer, trees, and landscapes, some with light colour washes. The pictures show a designer simple, economical line work with sparse washes of green and blue, and framed panels that divide a page into scenes.
