Create a flashback scene to 1955, depicting a cold winter night in Montgomery, Alabama, with a quiet street, a vintage bus, and snowfall. The atmosphere is somber and thoughtful, with smaller flurries falling gently, reflecting the historical significance of the scene. The vintage bus has unique, historical features such as the route displayed on the front, era-appropriate advertisements, and seating arrangements. Apply a realistic, detailed style, accurately depicting the vintage bus, environment, and weather conditions. The scene takes place on a cold winter night, with snowfall, ice, and frost covering the surroundings, enhancing the atmosphere.
