A cheerful summertime food-truck festival poster, vertical 18x24 inch format, in a punchy retro pop-art style. Center: a flat illustration of three side-by-side cartoon food trucks parked on a wavy bright-yellow road, each truck a different color (tomato red, mint green, baby blue), each with a small chalkboard menu hung on the side reading "TACOS", "BAO", "DUMPLINGS". A grinning sun with sunglasses peeks from the upper-right corner. Confetti bursts and tiny stars sprinkle the sky. Typography: a fat hand-drawn slab-shadow display face along the top in two arcing lines, "BIG / FORK FAIR"; below the trucks a clean retro grotesque caps line "twelve trucks, two stages, all day". Bottom info bar in a thick black band with cream text: "SATURDAY JULY 13 / 11 AM TO 9 PM / RIVERFRONT LAWN / FREE ENTRY". Tiny ticket-stub icon in the corner. Mood: loud, friendly, neighborhood-fair joy, deliberately a little tacky in the best way.
