New York: The John Weber Gallery, 1974. First Edition. Small square quarto. Artists' book by Sol LeWitt, consisting of a series of illustrations of unenclosed cubes with four to nine edge pieces. Each spread features two renderings, a photograph and a graphic drawing, of the same configuration. The subject of numerous international exhibitions, this series was one of the first by LeWitt to explore the cube, a form that would later become central to his practice and artistic language.
