Upon graduating, Claus relocated to Hanover in 2006. Since then his work has been on show at numerous fairs and exhibitions in Germany and abroad. Claus's main passion has been pushing the boundaries of Calligraphy; he is considered to be among Germany‘s top league calligraphers. He combines his distinguished writing with many facets of life and art: he writes and illustrates poetry and texts, combines silkscreen print, painting and writing to multi-layered unique tableaus and works with anything and everything that can be written upon towards installation pieces. His artwork has found wide-ranged recognition by private collectors and galleries in Germany and abroad.
