Poster Quảng Cáo Nước Giải Khát Cổ Điển

A bright, energetic retro commercial advertisement poster for a beverage popup stand. Top and center: an oversized, thick, rounded 3D theme logo reading "[Lychee Opening]" styled like soft inflated signage with a light color fill and clean edges, anchoring the upper visual hierarchy. Directly beneath it, the subtitle "[LYCHEE ICED TEA]" appears in a narrow, tall retro uppercase typeface. In the corner, small typographic detail reads "[Weekend limited 100 cups]". Handwritten italic decorative phrases, white line-drawn curved swooshes, sparkle flashes, and graphic accents swirl playfully across the composition. Lower center: [a cup of lychee iced tea close to the bottom, with lychee pulp and ice cubes inside, and a straw slightly sticking out]. The beverage features a realistic commercial product photography look with glistening condensation droplets, liquid luster, and natural shadows overlapping the background and text. Background and palette: dynamic graphic radial color blocks exploding outward from behind the cup with sharp edges; high brightness and saturated yet clean colors inspired by the beverage flavor.
