The Fine Arts Squad produced another mural during the painting of Isle of California. This painting, an illusion entitled Hippie Know How, took only six weeks to complete. Leonard Koren, acting as promoter, secured a commission from the French Government for the Biennale de Paris 1971. Henderson, Schoonhoven, and Koren worked on the painting, as did Paul Martin, a French artist who joined the group for this one project.
