H. Heyman's and G. E. Scheyer's letter to Sidney Janis

H. Heyman, on his own behalf and on behalf of G. E. Scheyer, writes to Sidney Janis, director of the Organising Committee for the exhibition Picasso's Guernica, for the Spanish Refugee Relief Campaign, about the lack of information they have received on the catalogues and recordings made on Guernica, as well as their awareness that the Motion Pictures Artists' Committee has kept the profits from the exhibition.
