The Wall Drawing concept was the best medium for giving expression to LeWitt’s radical ideas, and these works would become the most characteristic in his output. In a 1970 text under the same name, Wall Drawings, the artist explained that his approach consisted of making a work “as two-dimensional as possible”. In accordance with his minimalist, and therefore reductionist, thinking, LeWitt felt the most natural way to work was directly on the wall, rather than on a “construction” which would later be hung on the wall. This enabled him to create works with a minimum of materials, allowing the drawing to become an intrinsic part of the architecture of the gallery and causing the viewer to interact spatially given that they would only make sense of the work through experiencing the actual exhibition space.
