This is based on a photo by Michael Cooper (a prominent 1960s photographer), showing David Hockney standing in front of another Cooper photo called Spanish Interior. This is presumably the source of Blake’s title; the setting is maybe a Hollywood party, synonymous with glamour and artificiality. The figure in tight shorts gives Cooper’s original image homoerotic overtones, but Blake’s addition of party balloons and glitter seems to lighten the mood.
Michael Cooper is best known for his photos of the Rolling Stones. He also collaborated with Blake on the cover for the Beatles’ album Sgt Pepper’s Lonely Hearts Club Band.
