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.

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.

[Some people] put their work on the internet and check every day how many people look, how many people made contact, but I don't have internet, I don't have a hand-phone, I don't have fax, I don't have email. I just have old-fashioned telephone and letters.

I work on a political subject quite often, and the paintings, for me, are not finished until they're printed.

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