Claus was a very gifted Flemmish artist who had one specialty… he made almost exclusivily drawings and within these drawings he rarely used color. This made his work highly recognizable and because of the size of the drawings , some very nice publications were published. These artist books have now become very desirable and highly collectable books and http://www.ftn-books.com is lucky to have several titles available.
Claus was a master in creating an empty space with just a single form within. One of his favourites was a head on a rectangular plinth. With this drawing he creates an image of a sculpture but which was `ctually just a 2d drawing. Claus left about 30 sketchbooks in which it is made clear how he searched for abstraction.
