I just found this photo of Keith Haring painting on ffffound.
I saw more of his work in the Pop Life exhibition at the Tate Modern on Sunday. His Pop Shop was ace, in fact, I was pretty impressed by the whole exhibition. I'm not normally much of a Damien Hirst fan, but I was intrigued by the recreation of his work from the 1992 Cologne Unfair Art Fair, where a pair of identical twins sat beneath 2 of his spot paintings. I'm not sure if it was the fact that they looked at you but didn't speak, or that whenever I looked at them, they looked up at me, but it was a pretty disruptive experience in the show and one i'd recommend going to see.
