一筆画譜 ３編
This is a Meiji-era Japanese picture book (ehon) titled Ippitsu Gafu, third volume, compiled by Tani Sōtarō and published in 1881 by Matsuda Bunshodō, likely for readers learning to draw quickly with a single brushstroke. Its woodblock pages show figures, animals, and objects in bold black ink silhouettes with minimal shading, and a designer might take from them the economy of a continuous line and the strong figure-ground contrast of brush-and-ink drawing.
