Perhaps the choice is a negative one, in that I was trying to avoid everything that touched on well-known issues - or any issues at all, whether painterly, social or aesthetic. I tried to find nothing too explicit, hence all the banal subjects; and then, again, I tried to avoid letting the banal turn into my issue and my trademark. So it's all evasive action, in a way.

My pictures are devoid of objects; like objects, they are themselves objects. This means that they are devoid of content, significance or meaning, like objects or trees, animals, people or days, all of which are there without a reason, without a function and without a purpose. This is the quality that counts. Even so, there are good and bad pictures.

When I look back on the townscapes now, they do seem to me to recall certain images of the destruction of Dresden during the war.

I wanted to make it as anonymous as a photo. But it was perhaps also the wish for perfection, the unapproachable, which then means loss of immediacy. Something is missing then, though; that is why I gave that up.

What attracted me about my mirrors was the idea of having nothing manipulated in them. A piece of bought mirror. Just hung there, without any addition, to operate immediately and directly. Even at the risk of being boring. Mere demonstration. The mirrors, and even more the Panes of Glass, were also certainly directed against Duchamp, against his Large Glass.

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.
