Boston: Ginn, 1907. First edition. Hardcover. 162p, no ills. Covers lightly rubbed, paper label browned. From the library of a professor Cross, with his pencil name and with a gift card laid in. Perhaps a later printing? (copyright line reads 66.12). No jacket (as issued?). Very good. Item #30289
Originally published in the scientific supplement of the Munchener allgemeine Zeitung. Non-technical explanation of the chemical and physical properties of various drawing and painting media (pencil, crayon, pastel, fresco, oils, watercolor, tempera), and how artists can benefit from understanding their interrelationships with the optics of color, pgments, supports, etc. "In art also unconscious inspiration must give way to conscious understanding." Small but very informative. Can be sent outside the US for less than the default shipping rate.
