The Red Ballon is a oil painting on muslin primed with chalk and was painted by Paul Klee (18 December 1879 – 29 June 1940) in 1922.
He was a Swiss-born German artist. His highly individual style was influenced by movements in art that included expressionism, cubism, and surrealism. Klee was a natural draftsman who experimented with and eventually deeply explored color theory, writing about it extensively; his lectures ‘Writings on Form and Design Theory’, published in English as the ‘Paul Klee Notebooks’, are held to be as important for modern art as Leonardo da Vinci’s ‘A Treatise on Painting’ for the Renaissance. His works reflect his dry humor and his sometimes childlike perspective, his personal moods and beliefs, and his musicality. Wikipedia
