A Happy Hippie Hitler

The brothers [Jake and Dinos Chapman] unveiled 13 of Hitler's watercolours, on which they had added psychedelic rainbows, stars and love hearts.

"If hell exists and Hitler exists in it, he would be spinning if he saw these. It's not his work any more. It's our work," they said.

"The idea is to reverse the meaning and experience of bullet holes [in Beirut] and to introduce unexpected poetic moments of beauty, ambivalently mixed with the physical testimonies of violence. "
