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.

... landscapes or still-lifes I paint in between the abstract works; they constitute about one-tenth of my production. On the one hand they are useful, because I like to work from nature - although I do use a photograph - because I think that any detail from nature has a logic I would like to see in abstraction as well.

These pictures possibly give rise to questions of political content or historical truth. Neither interests me in this instance. And although even my motivation for painting them is probably of no significance, I am trying to put a name to it here, as an articulation, parallel to the pictures, as it were, of my disquiet and of my opinion.

Unlike the photography and prints, I never catalogued, kept track of or exhibited the sketches. I sold some occasionally, but never saw myself as a graphic artist. They became more important to me thanks to the exhibition, however, and I realized that these drawings were quite interesting after all.

I've never found anything to be lacking in a blurry canvas. Quite the contrary: you can see many more things in it than in a sharply focused image. A landscape painted with exactness forces you to see a determined number of clearly differentiated trees, while in a blurry canvas you can perceive as many trees as you want. The painting is more open.

That was a piece I did in 1963 with Konrad Lueg in a department store, in the furniture department. It was announced in some papers as an exhibition opening, but the people who came didn't know that it was to be a sort of Happening. I don't think it is quite right that it has become so famous anyhow. It was just a lot of fun, and the word itself, Capitalist Realism, hit just right. But it wasn't such a big deal.

Only about one per cent of my paintings show family members. Do they help me deal with problems? It's likely that these problems can only be depicted. But photographs, private ones and others, keep appearing that fascinate me so much that I want to paint them. And sometimes the real meaning these images have for me only becomes apparent later.
