cinematic realism 1930s Cars in Period Settings Citroën Traction Avant - Paris, Dawn A sleek black Citroën Traction Avant moves quietly along the cobblestone streets of Montmartre as dawn breaks over Paris. Morning mist clings to the ground as a few early risers - bakers carrying fresh bread, flower sellers arranging their carts - prepare for the day. The car's innovative front-wheel drive allows it to navigate the narrow streets with ease. A police officer eyes the vehicle suspiciously from a café doorway - these modern, fast cars are popular with both the bourgeoisie and the criminal underworld. Inside, a man in a tailored suit checks his watch impatiently while his driver navigates toward the Seine.
