Attributed to Willem de Kooning, American, Dutch, German, 1904 to 1997, mixed media, mostly oil, painting on cardboard depicting an Abstract Expressionist composition with a door. Framed. Willem de Kooning is a leading artist and sculptor of the second half of the 20th century, one of the leaders of Abstract Expressionism. De Kooning used a variety of tricks to pump up the sensuously inviting tactility of his surfaces, including his famous wet on wet technique of mixing salad oil in the pigment, in order to make it slithery, fluid and receptive to sustained periods of work. It didn't dry out fast. As he worked he would repeatedly scrape down the surface, leaving layered smears and traces of underpaint to show through, like insistent memories of past encounters piling up one on top of the other. His paintings can look slatternly, as if they've been around. He rarely painted either males or reclining figures. One of a kind artwork.
