Study of Artillery Cannon (Begonnene Studie einer Artilleriekanone) [p. 1] 

This pencil drawing by German Expressionist Max Beckmann is a study of an artillery cannon. Created sometime between 1914-1918, the sketch depicts a cannon barrel pointing upward, with two wheels and a few details of the firing mechanism visible. The piece, likely a preparatory study for a larger work, reflects Beckmann's experiences during the First World War and the powerful impact of weaponry. This sketch is part of a larger sketchbook, which also includes other drawings and studies of war-related subjects.
