Daniel-Henry Kahnweiler, gallerist and a friend of Picasso’s, sends Willem Sandberg, director of the Stedelijk Museum, Amsterdam, a copy of the letter in which the painter gives his consent to loan Guernica to the exhibition being organised by the Dutch museum and the Palais des Beaux-Arts, Brussels. He informs him that the painting will be available in May and he will have to reach an agreement with Robert Giron, director of the Belgian museum, to ensure the rest of the works arrive from the USA in time, and also notifies him that there is the possibility of extending the exhibition to the autumn of 1956 given that Picasso has set no time limit.
