Transform the provided travel photo into a stylized travel postcard. Preserve the landmark/scene as the clear focal subject; straighten horizon, crop to postcard framing (landscape 3:2 when possible) with balanced rule-of-thirds and breathing space for typography. Add subtle depth of field and gentle vignette; fine film grain and light paper texture; crisp, clean detail.
Apply a Postcard Style treatment: era-appropriate paper (linen or matte), slight halftone/print misregistration, mild edge wear. Use a Color Tone color filter suited to the scene; natural light with a soft golden glow. Add a vintage postcard border (off‑white with deckled or perforated edge, rounded corners). Overlay headline text "Postcard Title" prominently in period‑matching type with soft drop shadow/emboss; include small stamp box and circular postmark in a corner; tasteful light leaks or sun flare. Output a refined, high‑detail, print‑ready image.
