The first two pictures are chalk drawings from about 1984. At that time I was devoted to photographic realism, and I have loved this technique with the dull, black colours and the high contrast ever since. My living room is covered all over with such pictures.

I did hundreds of pencil drawings in numerous courses for nude drawing and portraits.

Pen-and-ink-drawings are most difficult. If you draw yourself you will know that you can't erase anything here. Every stroke must - or should - be accurate. The three drawings below were done by using this technique.
