Cubism is a poster highlighting the 2014 exhibition at the Metropolitan Museum of Art in New York entitled Cubism: The Leonard A. Lauder Collection. The exhibition traced the invention and development of Cubism using iconic examples from the Leonard A. Lauder collection. Cubism was the most influential art movement of the 20th century: it radically destroyed traditional illusionism in painting, revolutionized the way we see the world (per Juan Gris), and paved the way for the pure abstraction that dominated Western art for the next fifty years.
