Alternate Not-Straight Lines (From the Right Side) and Broken Lines (From the Left Side) of Random Length 1972

"Alternate Not-Straight Lines (From the Right Side) and Broken Lines (From the Left Side) of Random Length" is a 1972 work by American Conceptual artist Sol LeWitt (1928–2007). The piece, executed in graphite on paper, consists of countless thin lines, some straight, some broken, some curved, which are applied in a seemingly random fashion over the surface of the paper. LeWitt's conceptual art, with its emphasis on ideas and the instructions for their execution, is a prime example of Minimalism, a style that rejects expressive gestures in favor of geometric forms and minimalist composition. The title of this work describes the process of the art, highlighting the artist's use of pre-determined instructions to execute the work.
