Create a bold retro pop-art poster for a Blueberry Dessert Shake. Use a thick blueberry shake in a transparent glass with dripping syrup, whipped cream swirl, blueberries, mint leaf, and a colorful straw. Theme: 90s retro diner poster Colors: bright magenta, electric blue, cream, purple, hot pink Background: halftone dots, vintage paper texture, bold geometric shapes, sticker-style cutout behind the glass Typography: huge stacked text saying “BLUEBERRY BLAST”, with smaller text “COLD. SWEET. CREAMY.” The text should wrap around the shake with a fun diner-style design. Make it bold, playful, high contrast, realistic but with retro printed poster texture. Add glossy syrup, realistic whipped cream, fresh berry details, and strong commercial lighting.
