Affiche d'Été Rétro Pop Art de Yokohama

A vibrant retro Japanese pop-art travel poster for [Yokohama] in a bold comic-book style with thick black outlines, saturated summer colors, halftone dot textures, and crisp cel shading. Composition & Setting: Vertical poster layout. The background depicts the [Yokohama] waterfront: blue bay with railing, a skyline of modern high-rises, a large Cosmo Clock-style ferris wheel on the left, historic red brick warehouses on the right, and a harbor promenade. Two tall palm trees frame the scene under a bright cyan sky filled with white clouds, seabirds, and dynamic speed lines. Behind the characters sits a glossy [pink] 1950s American convertible with chrome bumpers, grille, headlights, whitewall tires, and a small front plate reading “YOKOHAMA SUMMER”. Flower planters sit near the car, and a single pair of pink sunglasses lies on the pavement in the bottom-left foreground. Characters: In the main foreground stand exactly two characters: 1. A cute chibi zombie girl with pale blue skin, a black bob haircut, visible stitch marks on her face and limbs, large round black-and-white eyes, and a cheerful open smile. She wears a pink short-sleeved dress covered in white hearts with black trim, white socks, and black Mary Jane shoes, flashing a peace sign with one hand. 2. Beside her stands a tall friendly robot named [Chappie], featuring a sleek silver and charcoal humanoid body, rounded shoulder armor, black mechanical joints, and green glowing cable accents with a green emblem on the chest. One hand rests on its hip, while the other holds a green glass soda bottle labeled “SODA” with a red-and-white straw. Its face is obscured by a neutral gray rectangular censor bar. Typography & Details: - At the top, stacked headline text: “YOKOHAMA” in huge hot pink block letters with white and black outlines, “POP” in oversized yellow halftone letters, and a tilted white ribbon banner reading “SUMMER CITY” in blue. - Directly below, a starburst badge labeled “ZOMBIE GIRL & CHAPPIE” in pink, blue, and green. Constraints: Highly detailed collectible poster composition, no extra characters, and no additional large text beyond the specified typography.
