Mary Patten painted Douglass Street Mural – Cityarts Workshop’s first Brooklyn-based project – in 1976. Over a five-month period, Patten led a group of 20 teens and adults to develop various themes for the mural that would be located on Douglass Street in the Park Slope area of Brooklyn - an area more commercial than residential at the time. Community meetings and bilingual flyers filled the neighbourhood in the hope of garnering community input and consensus over the choice of imagery.  The three-storey mural takes advantage of the building's structure by presenting the image as book pages waiting to be read. The dystopian nightmare to the right-hand side of the mural attempts to encroach on the multicultural utopian melting pot to the left, only to be fended off by workers and important figures from U.S. history. Folded into the Puerto Rican flag and the red, white and green banner of the African National Congress, are the images of Harriet Tubman, pointing towards the nightmare-scape, alongside Frederick Douglass, Lolita Lebrón, Malcolm X and H. Rap Brown. Under the imperialist eagle and puppet-like figure in its talons, Patten depicts a recent firebombing that had destroyed the homes of several Black families a few blocks away. Speaking of the large rainbow in the image, the muralist incorporated it to show "what is possible when people work and fight together to create what we need: a community school that provides quality education; people sharing skills and tools; dancing together; making music and painting a mural."The mural sought to convey hope and determination in the face of oppression. But by the 1980s, the mural had become obscured by new housing developments.
