天楳画譜
Tenbai gafu is a Meiji-era Japanese picture manual of ink painting, written by Nagao Bokuboku and published in 1881 by Kobayashi Kichiemon and associates for amateur students of brush painting. Its pages show loose monochrome sketches of plants, rocks and flowers with calligraphic inscriptions beside them, so a designer could draw on the economical brushwork, bold black ink masses and open white negative space.
