Split-Vertical Travel Postcard: Seoul & Beijing

A split-vertical travel postcard aesthetic featuring a hyper-realistic sunset photograph on the left - framed by foreground cherry blossom branches, traditional East Asian architecture/rooflines with hanging lanterns or a traditional Korean flag banner, a calm reflective waterway with a arched bridge, and a modern skyline blending historic hills or imperial temples - torn vertically and joined to a textured cream-colored vintage postcard paper on the right. The right side features a retro postage stamp with a traditional building outline and city cancellation stamp, delicate watercolor botanical cherry blossom sketches, an expressive ink-wash/watercolor illustration of the iconic landmark (N Seoul Tower over hills or Temple of Heaven), handwritten cursive city name typography ("Seoul" / "Beijing"), catalog metadata ("No. 002, Seoul, South Korea, 2026"), a small ink heart sketch, and a subtle Chinese seal stamp (for Beijing).
