Wall Drawing 915 can be read as an amalgamation of many of Sol LeWitt’s formal themes from the 1960s through the 1990s. These include his rectangles within rectangles, a motif he first explored in the sculptural pieces from the 1960s, and circles and arcs he began to work with in the 1970s. The drawing also features framing devices, first employed in the 1980s, and presents the undulating wave forms from the late 1990s. The work’s palette consists of intense, brilliant hues. The two areas that have been left white refer back to the wall itself, reinforcing the flat surface plane and emphasizing the acrylic medium and saturated colors. Wall Drawing 915 is indicative of the increasingly expansive and playful compositions that the artist began to create in the 1990s.
