Create with GPT Image 2: A vertical 9:16 watercolor travel poster for Switzerland, styled like an elegant illustrated tourism print on textured cream paper. Compose a quiet Swiss lakeside street scene with cobblestone pavement, old European building facades with flower boxes, a church clock tower, a vintage tram on the street, cafe tables, pedestrians in coats, a bicycle in the foreground, and a calm lake edge to one side. Place dramatic snow-capped alpine mountains in the background under soft pale daylight. Use delicate transparent watercolor washes, fine ink details, gentle grey-blue shadows, warm pastel building colors, and a refined nostalgic travel-poster layout. Add tasteful poster typography at the top reading "SWITZERLAND" with a small subtitle "Quiet Streets & Alpine Light". Include small travel-print details such as a postcard stamp motif, city names like Zurich, Lucerne, Geneva, Interlaken, and Montreux, and a small lower vignette of a lakeside village and sailboat. Keep the design polished, airy, romantic, and editorial, with generous white space and a handcrafted watercolor texture. Avoid real store logos, luxury brand names, messy unreadable signage, watermarks, or modern advertising clutter.
