Here is France's June 14, 1955 thirty franc stamp (Sc #771) commemorating the Lumiere brothers and the 60th anniversary of French motion pictures.
From wikipedia, "The Lumiere brothers, Auguste Marie Louis Nicolas Lumiere and Louis Jean Lumiere, were French manufacturers of photography equipment, best known for their Cinematographe motion picture system and the short films they produced between 1895 and 1905, which places them among the earliest filmmakers."
