The Mountains of Husband and Wife (Onyo imoseyama 阥阦妹背山)
A Japanese woodblock-printed illustrated book by Katsushika Hokusai, published in 1810, showing a double-page spread of figures among stylised trees and pavilions. The pictures are ink line drawings with dense foliage, pagodas and robed figures, offering a designer a model for clean, rhythmic linework and layered landscape compositions.
