Par Avion Air Mail

Par Avion is the visual language of mid-century international airmail: the UPU-standard PAR AVION etiquette, the red-and-blue barber-pole envelope edge, and featherweight onionskin paper tinted cool blue-white to shave postage weight. Ink is strictly cool — royal blue, postal vermilion, navy-black — never warm sepia.

Everything is engineered for lightness and legibility across borders: condensed caps for addressing, typewritten correspondence, circular and wavy-line cancellation postmarks, and a crisp gridded layout that never rounds its corners or softens its geometry.

「航空邮简」复刻的是二十世纪中叶国际航空信件的视觉语言：万国邮政联盟统一的 PAR AVION 蓝色标签、信封边缘那条红蓝相间的「理发店转灯」斜纹，以及为了减轻 邮资而印在偏冷蓝白色葱皮纸上的轻薄质感。墨色一律冷调——宝蓝、邮政朱红、近黑 的藏青，绝不掺一丝暖褐。

整套设计都为「轻」与「跨语种易读」服务：压缩体大写字母用于地址栏，打字机字体 承载书信正文，圆形与波纹状的邮戳负责盖销，网格化的版面始终保持挺括的邮政几何， 从不把边角抹圆、从不使用柔和渐变。
