112 Prince Street, c. 1978.

Artists Richard Haas' first mural, on the north party wall of 112 Prince Street, is called "Soho Mural." It was completed in 1975 after Haas proposed his idea to Doris Freedman, who led City Walls Inc. Haas drew from his surroundings in SoHo, a neighborhood rapidly changing due to plans of urban redevelopment and large-scale construction that disrupted the cityscape and left an abundance of exposed blank walls in the area. The mural's building, at 112 Prince Street, is now listed as part of the SoHo Cast-Iron Historic District, though this designation came after the completion of Haas' work.

Haas worked with architect Hanford Yang to acquire drawings of the West facade, which he meticulously copied in oil paint onto the brick party wall of the building. Ada Louis Huxtable, renowned architecture critic for the New York Times, called the work "an exercise in art and wit and instant architecture," a year after it was painted. Her successor Paul Goldberger called Richard Haas "the great architectural muralist of our time" in 2000. Haas started a campaign to conserve his first piece of work, titled "Save 112 Prince," in 2015.
