Le 14 Juillet 1917. La fête des drapeaux

This French film shows a flag ceremony in Paris on July 14, 1917. Among others, President Poincaré can be seen honoring soldiers. "Le 14 Juillet 1917" was distributed in the 28mm format that Pathé Frères introduced in France in 1912 and marketed internationally. Unlike the 35mm nitrocellulose print commonly used for professional exhibition, the 28mm material was flame-retardant, allowing such "safety films" to be shown without fire precautions, such as in home theaters. Shortly after the end of the war, Pathé Frères stopped marketing 28mm film in favor of other formats for safety films; it was probably not even marketed in Germany due to the First World War.
