The collages I never wanted to sell. I thought it was a very private thing, so I kept the collages. Then, in the end, I had a big collage in the Pinault Collection in Venice and the director of the [Centre] Pompidou said, "Did you make big collages like this in the '60s?" I said yes, so he came to the studio and said, "Let's make an exhibition in the Pompidou."

Things are forgotten so fast today. Even if 1,000 people are slaughtered, the next day you forget. There has to be new news every day.

In the exhibition at Galerie Perrotin, they have the Sarajevo painting - I think it's very good to nail down this story of Pol Pot and other people, not all dictators but most of them.

I have very warm memories about New York, about the old times, mostly the '60s.

I lived on Fulton Street in an enormous studio - I needed a bicycle to get to the toilet, about half a mile between two streets - next to Wall Street.

I have been very lucky, I have won prizes and I've even won the lottery.

Every five, six, seven, eight, 10 years I do a raisonné. When it's printed in the book, it's finished.
