Imagine a collage frame that resembles a vintage suitcase, complete with intricate details and ornate hardware, filled with a collection of antique maps, old postcards, and sepia-toned photographs, with a few hidden compartments and secret drawers.

Design a modern collage frame with a minimalist aesthetic, showcasing a series of abstract shapes and geometric patterns in a bold color palette, with a subtle texture that resembles rough-hewn wood, and a few strategically placed images of urban landscapes and cityscapes.

Create a surreal collage frame featuring a dreamlike cityscape with towering skyscrapers, floating clouds, and a subtle gradient of pastel colors, with images of vintage cameras, film reels, and old photographs scattered throughout, as if they're being transported to a new world.
