McCollum is recognized as one of today?s leading contemporary artists. His work has been exhibited extensively worldwide. Recently, his work has appeared in exhibitions at the Whitney Museum of American Art in New York, The Museum of Modern Art in New York and the Pompidou Center in Paris, France. The current White House Twentieth Century American Sculpture exhibit also includes a work by McCollum. In this early work by McCollum, he divides the composition into rectangles that resemble bricks. He uses intersecting lines throughout the composition, which merge at some point and thus create a sense of resolution. The spaces created by the lines suggest a relationship between the precise lines and the spaces. This abstract geometric work on paper hints at McCollum?s later works that focus on duplication of objects. He has received widespread recognition for his duplicating works, which he began making in the 1970s.
