Frederick A. Praeger, NY, 1953
Originally published as Pädogogisches Skizzenbuch, no. 2 in the series Bauhausbücher (Bauhaus books) during Paul Klee's tenure as professor at the school. Translated by Sibyl Moholy-Nagy, the book derived from the basic design course, where the approach taken in the 43 lessons was scientific rather than abstract, as Klee dedicates himself to the task of helping students to learn to see. A cornerstone of visual education, though not perhaps the most entertaining read.
