Painted by Paul Klee in 1923, during the Cubism movement. Key characteristics of this movement includes the emphasis of the two-dimensional of the canvas and the appearance of broken objects and then reassembled. This work uses 2D shapes to create the triangle and it also seems to be cut up into pieces.
