As Johnny Thornton recounts, "I became aware of the police being called 'Pigs' during the 1960s in America, relating to the Anti-Vietnam War movement. In London, Oz Magazine, that had begun its life in my hometown of Sydney, was making waves and was very much of my own thinking. I decided to produce a surreal photograph turning the literal translation into an image. The pig's head came from Harrods, which was hardly anti-establishment and is a dichotomy in itself."
