He stands on a dock with his back to the viewer, one hand raised to a passing rowing boat. Walter Thor (1870 to 1929) was a German-born painter trained at the Munich Academy who worked in Paris. He made at least one poster for Griffon, a cycle manufacturer established in Courbevoie, Seine, in the late 1890s. It dates to the early 1900s.
On the poster
A man in a dark suit and flat cap stands on a wooden dock above the Seine, beside a teal-framed Griffon bicycle. He raises one hand toward a small rowing boat crossing the luminous yellow-green river. Trees and a boathouse stand on the far bank. The man is seen from behind and the bicycle in profile.
