Rouen's grand civic square unfolds in tinted early-century splendor: to the left, the neoclassical Hôtel de Ville with its colonnaded portico, and dominating the right, the soaring Gothic spire and flying buttresses of the Église Saint-Ouen — one of the finest Flamboyant Gothic churches in France — with a bronze monument rising from the cobblestoned Place. Pedestrians in Edwardian dress drift across the square, lending the scene an unhurried, gaslit-era charm. Labeled number 15 in red letterpress in the image, this tinted collotype or early photomechanical card belongs to a Rouen city series likely produced c. 1904–1910, when divided-back standards were being adopted across Europe. The reverse is a classic French "Carte Postale" divided-back layout with the bilingual notice warning that some foreign countries do not accept correspondence on the address side — a hallmark of the transitional 1904–1908 period. Penciled "1oo" at top suggests a dealer's pricing or inventory mark.
