The museum collection holds almost 90,000 objects, collected since 1874.[25] With important clusters and cores focusing on De Stijl, Bauhaus, Pop Art and CoBrA and, more recently, Neo-Impressionism, the collection represents virtually every significant movement in art and design of the 20th and 21st centuries. The Stedelijk also has a comprehensive collection of drawings and paintings by Kazimir Malevich. Key pieces by Post-Impressionists Paul Cézanne and Vincent van Gogh exemplify art from the late 19th century.
