This catalogue raisonné, in four volumes, co-published par the Fondation Le Corbusier in Paris and the AAM editions in Brussels, presents and restores in their creative context some seven thousand drawings that Le Corbusier executed between 1902 and 1965. Each volume offers a documented journey through the history of this passionate and tireless cartoonist. For Le Corbusier, drawing is profound ment linked to intimacy, it is the t of 'things seen and retained'.
