In an attempt to explore the history of Sol LeWitt’s public projects and to record his long-lasting relationship with MoMA PS1, the artist created Crayola Square, a Crayola crayon wall drawing originally created in 1971 at an event organized by MoMA PS1 founder and director Alanna Heiss. It was the inaugural exhibition for The Institute for Art and Urban Resources, known today as MoMA PS1.
