Dia’s presentation of wall drawings by Sol LeWitt from the late 1960s through the mid-1970s was selected by the artist himself. It highlights his monumental Drawing Series-Composite, Part I-IV, #1-24, A + B (1968), a four-color rendering of which is executed here for the first time. The version in graphite, part of Dia’s collection, has been on view in an adjacent gallery since 2003.
