The interaction of form and color became in his abstract works the major theme running through his oeuvre: “Even though every brushstroke represents for itself a transformed reality, it receives its true meaning in the context of surrounding shades of color.”

Towards the end of the 1930s the artist slowly gave up figurative painting, turning entirely to non-representational painting by 1943. Lanskoy’s success as an abstract painter was fully endorsed when he began a sixteen-year collaboration with Louis Carré, who was already showing Picasso, Matisse, Hartung and Soulages. In his continuous quest for new means of expression, he turned to the illustration of books, tapestries, mosaics and collages. André Lanskoy entertained a deep friendship with Nicolas de Staël, with whom he held a joint exhibition in 1948. During this time and the following decade, André Lanskoy gained international acclaim through exhibitions like the one of his latest works at the New York Fine Arts Associates in 1956.

Nowdays the artist is represented in numerous major public collections, including the Musée National d’Art Moderne, Centre Georges Pompidou, Paris; Musée d’Art Moderne de la Ville de Paris; Solomon R. Guggenheim Museum, New York; and the Museums of Modern Art of Antwerp, Mannheim, Philadelphia, Toledo, Colmar, Grenoble, Lille, Tourcoing, Le Havre, Saint-Etienne, Villeneuve-d’Asq and Mulhouse.
