25 x 16.5cm, 30pp. Original blue wrappers printed yellow. With seventeen plates (including tipped-in colour frontispiece by Chagall and a small b/w block print by Kandinsky as frontispiece) reproducing work by Kandinsky, Marc, Severini, Leger, Klee, Molzahn, Muche, Schwitters and others. A reprinted essay from Der Sturm as a separate pamphlet intended to promote those artists in favour at the magazine.

Walder was in fact the pseudonym of Georg Lewin, gallerist and the founder of Der Sturm and promoter of German and other expressionism. A VG example with only minor browning to the internal pages (printed on cheap paper) and some browning around the extremities of the oversize wrappers but this is as good an example as one is likely to find.
