A vintage 1970s Swiss tourism advertisement poster style. A low-angle close-up shot focusing on a woman's bare legs and feet standing in lush green summer grass at night. Direct focus on a sparkling sparkler (Wunderkerze) stuck in the ground right next to her feet, throwing bright golden sparks and a warm, glowing light onto her ankles. Only the colourful hem of her retro-patterned red and white summer dress is visible. The image has a distinct analog film grain, warm saturated colors, high contrast, and a soft vignette around the edges. In the dark sky background, faint festive lights blur into a soft bokeh. Clean layout, nostalgic Swiss summer night vibe, photorealistic 35mm film print style.
