Pierced with mounting holes at the corners. Composition and all lettering remain fully legible. Unframed.

Created for the launch of Léon Bailby’s nationalist daily Le Jour (first issue 3 October 1933), this enamel sign is one of the rare advertising objects designed by A.M. Cassandre, the foremost poster artist of the inter-war years (Étoile du Nord, Nord Express, Dubonnet, Normandie). The composition centres on a stylised solar eclipse — a dark sphere ringed with planetary orbits and stars, masking a radiant white sun whose ochre rays spread across a deep blue, airbrush-graded sky. Above, the title Le Jour is set in Cassandre’s signature geometric capitals over the line “Directeur Léon Bailby”; below, the slogan “Dit la vérité” and, lower right, “En vente ici.” The eclipse-and-light imagery works as a visual metaphor — day breaking, truth brought to light — translating Cassandre’s airbrushed modernism into vitreous enamel. Point-of-sale plaques of this design were displayed by newspaper vendors across France.
