Create a clean vintage travel poster illustration of {argument name="city name" default="GIFU"} in Japan, drawn as detailed monochrome line art in deep forest green ink on a warm ivory paper background. The composition is vertical and symmetrical, with one huge minimalist sans-serif headline reading {argument name="headline text" default="GIFU"} across the top, a detailed street-level view of the Yanagase covered shopping arcade below it, and one small bottom caption reading {argument name="bottom caption" default="岐阜市 JAPAN"}. Show the arcade entrance centered in perspective, with the main sign reading {argument name="arcade sign text" default="柳ヶ瀬"}, a long glass-and-metal arched roof receding into the distance, dense storefronts on both sides, hanging shop signs, traffic lights, utility poles, crosswalk stripes in the foreground, and mountains plus a small Japanese castle silhouette rising behind the buildings. Include a lively city scene with pedestrians, two schoolgirls with backpacks walking into the arcade at center foreground, one cyclist crossing left to right in the foreground, café seating on the left, and a woman in a skirt carrying a shopping bag on the right. Use fine architectural drafting lines, delicate hatching, manga-inspired urban detail, flat two-color printmaking style, no shadows except ink line texture, nostalgic tourism-poster mood, centered perspective, crisp typography, and a calm refined Japanese city-travel aesthetic. Add visible Japanese storefront signage including bookshop, coffee shop, Yanagase-dori, and small vertical shop signs, while keeping the overall palette limited to dark green and ivory.
