He spent most of the war trying to emigrate to the United States, an unsuccessful and costly enterprise that may have driven him to alcoholism. Upon his return to Paris, after the hype from the war had died down, he had his first exhibition of watercolors in December 1945 at the Galerie René Drouin, where despite the lack of commercial success he made an impression on the circle of intellectuals around the gallery. These included Jean Paulhan, Francis Ponge, Georges Limbour and André Malraux. The small works were displayed in light boxes. A second exhibition in the same gallery two years later saw greater recognition. His paintings represented a rejection of figuration and abstraction, and a projection into a metaphysical plane.
