Was there anything in the childhood of 20th century artists, designers and architects that could explain the ruptures of modern art? This exhibition, open from 22 March to 23 June at the Fundación Juan March in Madrid, attempts to answer this question. It does so by taking seriously the game of mixing drawing manuals and methods, materials and educational resources with the work of artists and designers such as Gris, Braque, Picasso, Mondrian, Kandinsky, Delaunay, Albers, Le Corbusier and 275 others.
