TASCHEN Mondrian by Susanne Deicher. Hardcover, 21 x 26 cm, 96 pages. A key figure in the international avant-garde, Piet Mondrian (1872–1944) was at once an extraordinary painter and leading art theoretician whose influence resonates to this day. Coining the term “Neo-plasticism”, he pursued a style of painting composed only of primary colors against a grid of black vertical and horizontal lines and a white base background.
