In 1946, de Kooning began a series of largely black and white paintings that culminated in his first solo exhibition at New York's Charles Egan Gallery in the spring of 1948. His use of synthetic commercial enamel for these works was an economic choice-as he told the critic Harold Rosenberg, "I needed a lot of paint…. I could get a gallon of black paint and a gallon of white paint-and I could go to town." On paper the enamel paint also dried quickly, allowing de Kooning to build up wafer-thin layers of experimental forms without worry that they would blend together. The restricted palette of black and white allowed de Kooning to experiment with a loose, Cubist-style abstraction, but remnants of the human figure remain underneath the swirls of paint.
