The author of the book De cómo Nueva York robó a París la idea de arte moderno (Madrid, 1990) and the curator of the exhibitionBajo la bomba: el jazz de la guerra de imágenes transatlántica, 1946-1956 (MACBA and Museo Reina Sofía, 2007) talks about the new post-war scenario in dispute, in which there is a convergence of realism, abstraction and traces of an historical avant-garde that shows clear signs of exhaustion.
