This is Fritz Bultman's Palm II.

In 1933, he opened the Hans Hofmann School of Fine Arts in Manhattan. He opened a summer school in Provincetown, MA the following year and hence divided his time between the city and the coast. He continued to teach in both New York and Provincetown for the next twenty-eight years.  As told in his book “The Search for the Real and Other Essay,” published in 1948, Hofmann produced a new type of landscape, one composed not of trees and land, but of the tension between space, form, color and planes.   - Julie Heller
