This drawing depicts two pieces from a series of works entitled Icons, which were hand-crafted by the artist in the early 1960's. Made of painted wood and incorporating incandescent or fluorescent light, these pieces were early explorations of light, and show Flavin's concern with placement and composition in an architectural space. These ideas were fully developed in his large-scale installations of fluorescent lights. The drawing is signed on all four edges, indicating that the works could be viewed from any side.
