The Block Collects: Sol Lewitt, Wall Drawing 215

February 4-June 14, 2026
Inside Main Gallery
Sol LeWitt (American, 1928 - 2007), Wall Drawing 215 [detail], September 1973, (first installation), Black crayon on wall, dimensions variable, Mary and Leigh Block Museum of Art, Northwestern University, gift of Steven P. Henry and Philip Shneidman, 2021.12

Sol LeWitt’s Wall Drawing #215 is a site-specific “location drawing” realized directly on the gallery wall through a set of written instructions. Dependent on the dimensions of the space, the work takes shape through careful plotting, drafting, and execution by trained installers, emphasizing LeWitt’s belief that the idea behind a work of art is as essential as its final form. This installation invites close looking and reflection on process, precision, and collaboration.
