From very young Claude Viseur has always been drawing even in his copy-books and was sometimes punished for that.

In 1967 He started his professional life in the Belvision Studio in Brussels and participated in the creation of cartoons (Asterix with Goscinny and Uderzo, Lucky Luke with Morris, Tintin with Hergé…). At that time he chose the nickname Clovis (short of his first and second names).
He had been a racing car fanatic for a long time and soon started collaborating in some Belgian racing car magazines.

In 1974 he met Jean Graton, joined his cartoonist team and became responsible for the design and drawing of Michel Vaillant’s cars. Meanwhile he started having contacts with sponsors and racing cars companies who asked him more and more illustrations.

In 1982 he left Jean Graton and started his real free-lance life. He worked as a mercenary always ready to challenge with too short deadlines whether it be for a comic strip, a cartoon, a realistic or humoristic drawing or painting.

In 2004 he published the book Historickx dedicated to Jacky Ickx’career and in 2005 3 books for children telling the story of Nioubi, a nice little car.

He died in 2018 leaving behind a huge number of drawings and paintings.
