复古函馆旅行海报

Create a vintage Japanese travel poster for {argument name="destination city" default="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 {argument name="Japanese headline text" default="函館"}, a widely spaced romanized title beneath it reading {argument name="romanized title" default="HAKODATE"}, and a bottom caption between two thin red horizontal rules reading {argument name="bottom caption" default="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.

创作一张复古风格的日本旅行海报，主题为 {argument name="destination city" default="日本函馆"}，背景采用带有细微折痕、污渍和磨损边缘的暖色调旧米色纸张。构图采用垂直居中布局，包含三个主要文本元素：顶部为醒目的黑色粗体日文标题 {argument name="Japanese headline text" default="函馆"}，下方为字母间距较宽的罗马拼音标题 {argument name="romanized title" default="HAKODATE"}，底部为位于两条细红横线之间的说明文字 {argument name="bottom caption" default="日本 / HAKODATE, JAPAN"}。在标题下方，绘制一幅复古线条风格的详细街景，采用柔和的米色、黑色墨水以及克制的红色点缀：一条带有电车轨道的笔直城市街道，以一点透视法向远方延伸，两侧是带有竖向店招、灯笼、遮阳篷、架空电线、交通信号灯、红色邮筒、自行车、行人和两辆行驶车辆的低矮日式店面。背景处描绘一座宽阔的棕色山峰矗立在城镇后方，山顶设有高大的观景塔和一座较小的红色塔楼，以此呈现函馆山风貌。采用清晰的建筑钢笔线条、极简的平涂色彩、昭和时代的怀旧平面设计风格、旅行指南海报美学、整洁的居中布局，且不追求照片级真实感。
