I find the Romantic period extraordinarily interesting. My landscapes have connections with Romanticism: at times I feel a real desire for, an attraction to, this period, and some of my pictures are a homage to Caspar David Friedrich.

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.

I see the bomber pictures as an anti-war statement... which they aren't - at all. Pictures like that don't do anything to combat war. They only show one tiny aspect of the subject of war - maybe only my own childish feelings of fear and fascination with war and with weapons of that kind.

The smudging makes the paintings a bit more complete. When they're not blurred, so many details seem wrong, and the whole thing is wrong too. Then smudging can help make the painting invincible, surreal, more enigmatic - that's how easy it is.

Composition is a side issue. Its role in my selection of photographs is a negative one at best. By which I mean that the fascination of a photograph is not in its eccentric composition but in what it has to say: its information content. And, on the other hand, composition always also has its own fortuitous rightness.

The paint for the grey paintings was mixed beforehand and then applied with different implements - sometimes a roller, sometimes a brush. It was only after painting them that I sometimes felt that the grey was not yet satisfactory and that another layer of paint was needed.

The desire to please is maligned, unfairly. There are many sides to it. First of all, pictures have to arouse interest before people will even look at them, and then they have to show something that holds that interst - and naturally they have to be presentable, just as a song has to be sung well, otherwise people run away. One mustn't underrate this quality, and I have always been delighted when my pieces have also appealed to the museum guards, the laymen.
