Details: This poster is of Senecio (Old Man), 1922, by Paul Klee.
Paul Klee (18 December 1879 - 29 June 1940) was a Swiss painter of German nationality. His highly individual style was influenced by many different art trends, including expressionism, cubism, and surrealism. He was a student of orientalism. Klee was a natural draftsman who experimented with and eventually mastered color theory, and wrote extensively about it. His works reflect his dry humor and his sometimes child-like perspective, his personal moods and beliefs, and his musicality. He and his friend, the Russian painter Wassily Kandinsky, were also famous for teaching at the Bauhaus school of art and architecture.
