Mondrian writes that he prefers not to show old works at important exhibitions. Therefore, he did not want to participate in an American Abstract Artists (AAA) exhibition. To AAA, founding member Gertrude Greene (1904 – 1956), Mondrian writes, "I am glad to hear you and [Balcomb] both are well. I shall send the $4 dues to Mr. Cavallon. I am very sorry about not showing at the A.A.A. but I don't like to come with old works at a such [sic] important exhibit. Harry Holtzman is still in Kansas waiting for the service, I think. I did not hear from them. Hoping to meet you again at the opening A.A.A….” . Gertrude and husband Balcomb Greene (1904-90) were active proponents of Abstract Art working with the AAA committee. Gertrude, an abstract painter and sculptor, worked as a gallery attendant at the AAA's first annual exhibition and was the group's first paid employee. Balcomb served as the first president of the AAA whose members included Willem De Kooning, Ad Reinhardt, Lee Krasner, Holtzman who like Mondrian emigrated to the US. SIGNED, "Piet Mondrian," and again."P. Mondrian," in the envelope's return address. The letter is slightly trimmed at the bottom edge.
The American Abstract Artists was formed in 1936 in New York City and through its exhibitions, publications, and lectures advanced the understanding of the new art. Harry Holtzman (1912 – 1987) was an American artist and founding member of the AAA. He was executor of Mondrian’s Estate and in 1983 co-edited a volume of Mondrian’s complete essays. During the German Blitz of London in 1940, Holtzman arranged for Mondrian to come to New York, where he arrived that October. Giorgio Cavallon (1904–1989) was a founding member of the AAA and a pioneer Abstract Expressionist.
