This work is one of the early “painted constructions” included in Donald Judd’s first solo exhibition of three-dimensional works, at Green Gallery, New York (Don Judd, December 17, 1963–January 11, 1964). This piece originally incorporated a found object: a parallelogram-shaped metal lathe. For Judd’s 1975 retrospective at the National Gallery of Canada, the top of the work was removed, shipped to Ottawa, and installed on a newly constructed base. That work remains in the National Gallery of Canada’s collection. Meanwhile, a new top, made of aluminum coated in black enamel, was added to the existing base, which Judd installed in Marfa. Judd frequently used parallelograms in his woodblocks and woodblock prints.
