一筆画譜 ２編
This is a Meiji-era Japanese picture manual, the second volume of Ippitsu gafu, compiled by Tani Sōtarō and published in 1881 by Matsuda Bunshodō for students of brush drawing. Its woodblock pages show chrysanthemums, irises, fish and wildflowers in simplified single-stroke ink outlines with minimal shading. A designer could take from it the economy of a few confident brush lines, with negative white space doing much of the work of describing form.
