城市冰箱贴旅行海报

create a matching travel poster image divided into two parts (top and bottom), in the style of a 'city check-in / fridge magnet' souvenir. 【Layout Structure】 Use a vertical 3:4 composition, divided into two sections: • The top section uses a simple solid-color background. • The bottom section keeps the original photo completely unchanged. 【Top Section: Fridge Magnet Icon】 Extract the most recognizable subject element from the real photo in the bottom section: 1. Keep the original outlines, colors, and recognizable features. 2. Design it like a travel souvenir fridge magnet. 3. Add sharp edges and a metallic border. 4. Place the icon in the center. 5. Leave plenty of empty space around the icon. 【Background Color】 The top background color should be a solid color taken from the dominant tone of the original image. 【Overall Style】 The final result should look like a stylish travel photo card / souvenir postcard.
