Hands, are the most honest part of the human body, they cannot lie as laughing eyes and the mouth can.

I might be in the basement. I'll go upstairs and check.

All my works are games, serious game.

I am always wandering around in enigmas. There are young people who constantly come to tell me: you, too, are making Op Art. I haven't the slightest idea what that is, Op Art. I've been doing this work for thirty years now.

It is human nature to want to exchange ideas, and I believe that, at bottom, every artist wants no more than to tell the world what he has to say.

I try in my prints to testify that we live in a beautiful and orderly world, and not in a formless chaos, as it sometimes seems.

I believe that producing pictures, as I do, is almost solely a question of wanting so very much to do it well.
