The 44c stamp in the middle is from Abstract Expressionists issued in Mar.2010 featuring Willem de Kooning's work "Asheville".
Abstract expressionists believed that art no longer depicted experience but became the experience itself. They emphasized spontaneous, free expression and allowed personal intuition and the unconscious to guide their choice of imagery. Other shared traits include the use of large canvases and an emphasis on paint texture and distinctive brushstrokes.
Willem de Kooning (1904-1997) transformed the traditions of European art to create his own energetic and unconstrained style. While much of his work was entirely abstract, de Kooning’s best-known paintings blend abstraction and figural representation. Skittering black lines, shifting shapes, fragmented body parts, and flashes of color fill the surface of his 1948 work Asheville.
