This is Oliver Chaffee's Hills & Pine.

The "Armory Show" was a great and imposing demonstration of the newest and most important extreme in the modern art of the time. That was in 1913. Those who are interested in art history know that it was a time of Neo-Impressionism, Futurism, Cubism, and what not. And not alone in art. In the entire world order one felt a tense and feverish suspense. In the far reaches of the civilized world signs of the first World War appeared. - Geto-Motivin - Abraham Walkowitz - 1946

A major financial contribution toward making the Armory Show come to fruition came from the Buffalo heiress Mabel Dodge who helped seed the great early century migration from Greenwich Village to Provincetown in 1915. Amongst the works of Picasso, Matisse and Cézanne were five modernist artists who would soon join the history of Provincetown art: Oliver Chaffee, Abraham Walkowitz, Marguerite and William Zorach, and E. Ambrose Webster.
