Andrew Wyeth, born July 12, 1917, Chadds Ford, Pa., U.S, presented his first one-man show in New York City in 1937. The subject matter of Wyeth’s pictures comes almost entirely from two localities, the Brandywine Valley around Chadds Ford and the area near his summer home in Cushing, Maine. Wyeth uses a restricted palette mostly of earth colours but capable of hundreds of muted harmonies. His technique is precise and detailed, yet he lifts his paintings above photographic naturalism with an unreal, visionary quality. His best known painting, “Christina’s World” (1948; Museum of Modern Art, New York City), exemplifies his mastery of unusual angles of perspective and his use of light to pinpoint time.
