Steinlen is one of the great Art Nouveau artists, who is especially well-known for his strange depictions of cats, often full of supernatural energy. Still, a great portion of his art fell well outside the range of Art Nouveau, such as his wonderful Post-Impressionist pieces, which seem to have been inspired by Gauguin and Cézanne, and Expressionist works, which were perhaps inspired by Realists such as Millet. And yet, it's those cats which hold my interest to Steinlen and seem to best illustrate his originality.
