Alfred H. Barr Jr.'s letter to Nelson Rockefeller

Alfred H. Barr Jr., director of the Collections Department at the Museum of Modern Art, New York, informs Nelson Rockefeller that he has contacted Petro van Doesburg, the person in charge of the studio where his Guernica tapestry has been woven, to discuss the colours (in Pablo Picasso's view closer to the original than the actual painting, which has become slightly discoloured over time), and to inform him of his and the artist’s approval, in addition to asking him if he wants it to go on display in his museum when sufficient space becomes available.
