Le fusain sans maitre : traite pratique et complet sur l'etude du paysage au fusain
A French practical manual from 1897 by Karl Robert, published by H. Laurens in Paris, teaching students how to study landscape in charcoal. The plates are sideways-printed charcoal landscapes with trees, hillsides, water and sky, each captioned with its place name and artist credit. A designer could take from them the tonal range of soft smudged charcoal, with dense foliage masses against pale open skies and rough broken ground.
