Moscoso refers to this as his yin and yang or "sixty-nine" poster, describing how he used a T square, a triangle, and a compass to create the symmetry. "Here I took my psychedelic playbill to the max. This is definitely the apex of my psychedelic letter form. The idea just came to me. . . . The green and the blue are both referring to two different dances. Basically I used one poster to advertise two different shows."
