20世纪中叶建筑版画旅行海报

创作一幅精致的复古旅行海报插画，灵感来自20世纪中叶的建筑版画。将[LANDMARK]作为醒目、无可替代的中心主体，采用高度细致的手绘黑色墨线，表现复杂的结构细节、精巧的交叉排线，并带有真实的丝网印刷质感。为周围的树木、景观与微妙的建筑元素添加克制的深森林绿点缀色。

使用温暖的陈旧象牙白/奶油色纸张作为背景，带有微妙的天然纸纹、细小瑕疵、褪色的墨线边缘，以及真实的档案印刷感。保持构图对称、简约且留白充足，地标从画面下方中央醒目地升起。在其下方加入简单的复古风景：林荫大道、远处建筑以及柔和的几何透视。

在插画下方加入优雅的复古排版：

[CITY / LANDMARK]
No. [NUMBER] [SHORT DESCRIPTORS]
Year: 2026

排版应类似一份旧博物馆目录或1950s旅行档案：大写衬线标题、打字机风格的次要文字，并精心居中排布。不使用现代图形元素、不使用渐变、不使用摄影写实风格。真实的古董丝网印刷、精致的欧洲旅行海报美学、干净的构图、高度细致的墨线插画、略微不完美的套版错位、收藏级艺术版画，永恒而优雅。

Create a sophisticated vintage travel-poster illustration inspired by mid-century architectural printmaking. Feature [LANDMARK] as the unmistakable central subject, rendered in highly detailed hand-drawn black ink linework with intricate structural details, delicate crosshatching, and an authentic screen-printed texture. Add a restrained deep forest-green accent color to the surrounding trees, landscape, and subtle architectural elements.

Use a warm aged ivory/cream paper background with subtle natural paper grain, tiny imperfections, faded ink edges, and an authentic archival-print feel. Keep the composition symmetrical, minimal, and spacious, with the landmark rising prominently from the lower center. Add a simple vintage landscape beneath it—tree-lined avenue, distant buildings, and soft geometric perspective.

Below the illustration, include elegant vintage typography:

[CITY / LANDMARK]
No. [NUMBER] [SHORT DESCRIPTORS]
Year: 2026

Typography should resemble an old museum catalogue or 1950s travel archive: uppercase serif title, typewriter-style secondary text, carefully centered spacing. No modern graphic elements, no gradients, no photorealism. Authentic antique screen print, refined European travel-poster aesthetic, clean composition, highly detailed ink illustration, slightly imperfect registration, collectible art print, timeless and elegant.
