As a matter of fact, it was only through the dealer Fred Jahn that I succeeded in overcoming my reservation about the works on paper and exhibiting them. Added to this, of course, was the fact that after ten years I could see the watercolours in a different light, and in conjunction with pictures painted afterwards, they had at least become more comprehensible to me.

Maybe we didn't even have a chance. The message of American Pop Art was so powerful and so optimistic. But it was also very limited, and that led us to believe that we could somehow distance ourselves from it and communicate a different intention.

And then the work bears a strong sense of leave-taking for me personally. It ends the work I began in the 1960s (paintings from black-and-white photographs), with a compressed summation that precludes any possible continuation. And so it is a leave-taking from thoughts and feelings of my own on a very basic level. Not that this is a deliberate act, of course; it is a quasi-automatic sequence of disintegration and reformation which I can perceive, as always, only in retrospect.

Now there are no priests or philosophers left, artists are the most important people in the world.

A student researching into my work has actually traced the newspapers and magazines where I found theses images and has found out that many of them illustrate a collection of gruesome stories, murders and suicides which contrast with the images used. There is a contrast between the message carried by the text and that suppressed by the illustration.

I don't believe in the reality of painting, so I use different styles like clothes: it's a way to disguise myself.

Art is the highest form of hope.
