Alfred H. Barr Jr.'s letter to Petro (Nelly) Van Doesburg, dated 20 February 1956

Alfred H. Barr Jr., director of the Collections Department at the Museum of Modern Art, New York, discusses the the colours in the replica Guernica tapestry and does not feel they are closer to the original than the actual painting, which in his view hasn't changed. He also asks how the colours were chosen.
