Vintage Hakodate Travel Poster

Create a vintage Japanese travel poster for Hakodate, Japan on warm aged cream paper with subtle folds, stains, and worn edges. The composition is vertical and centered, with three main text elements: a large bold black Japanese headline at the top reading 函館, a widely spaced romanized title beneath it reading HAKODATE, and a bottom caption between two thin red horizontal rules reading 日本 / HAKODATE, JAPAN. Under the headline, illustrate a detailed retro line-art street scene in muted beige, black ink, and restrained red accents: a straight tram-lined city street receding in one-point perspective, flanked by low Japanese storefronts with vertical shop signs, lanterns, awnings, overhead power lines, traffic lights, a red post box, bicycles, pedestrians, and two cars driving along the road. In the background, show a broad brown mountain rising behind the town, topped by a tall observation tower and a smaller red tower, evoking Mount Hakodate. Use crisp architectural pen-and-ink outlines, minimal flat color, nostalgic Showa-era graphic design, travel-guide poster aesthetics, clean centered layout, and no photorealism.
