In this new volume, an essential group of 150 oils, watercolours, drawings and prints, representative of Klee's entire career, is released to the public for the first time. Offering new art-historical insight into Klee's career - from his early Impressionist-inspired works, through his Expressionism with Kandinsky and his Bauhaus period between the wars - this book contains the only reproduction of these important but little-known pieces collected by the Burgis, and will become essential to all enthusiasts of the art of Paul Klee and the modern period.
