画本両筆
This is a Japanese illustrated picture book (ehon) from the Edo period, published by Eirakuya Tōshirō and credited to Katsushika Hokusai and Naniwa Tatsuyoshi-sai. Its double-page woodblock views show landscapes with travellers, hills, pine trees and rice fields in soft blue and green washes. A designer might take from them the economical line work, open horizon spacing and layered pale colour that suggest distance across a flat plain.
