The museum’s post-1945 drawing and watercolor holdings are part of a large and strong collection of works on paper at the museum. An abstract expressionist gouache on paper by Jack Tworkov is complemented by a stunning ink and watercolor drawing by the sculptor David Smith, an oil pastel and oil paint drawing by Joan Mitchell, and a page with three ink preparatory sketches by Ralston Crawford, all from the 1950s. Works from the 1960s by well-known artists Eva Hesse and Agnes Martin are joined by fine drawings by Lee Bontecou, Walter Murch, and Charles White. Pop artist Larry Rivers and artist Leonard Baskin, who taught at Smith College for many years, also are represented in work from this decade. An important work from the 1970s is a two-part mixed-media work titled Running Fence by Christo. A drawing for a sculpture project by Alice Aycock is part of a series of gifts to the collection by Wynn and Sarah Ann Kramarky, as is the ink on paper work by Sol LeWitt and conceptual drawing by Morgan O’Hara. In the realm of contemporary Native American works linked to the tradition of ledger drawing, the museum has purchased a work by Linda Haukaas as well as a monumental drawing by Brad Kahlhammer. The museum is building its collection of contemporary African art as well, and one example is the recent acquisition of an expressive painting on paper by Twin Seven Seven.
