I live in Pittsburgh PA and am a regular visitor to the Warhol Museum, so I have seen some of Andy's oxidation paintings made with bodily fluids many times. They absolutely work as a piece of art, especially when you see them in a building full of completely different kinds of art in every medium from the same artist. I actually remember reading the descriptive placard the first time I saw them many years ago and thinking "What...the...f--k???", and then that word popped into my head. Genius. Why just use paint in an abstract expressionist style painting? I could easily imagine any one of them hanging in a conference room or a motel lobby. There was also that matter of making special copper based paint so that the process would even work.

By the way, if the Statue of David suddenly appeared in the middle of a square in Kabul, the Taliban would fire an anti-tank rocket at it. Nothing is universal.
