a mid-century retro pop poster (1950s-70s). SURFACE / STYLE: bold letters with thick black keyline outlines around flat, vibrant candy-color fills, a Ben-Day halftone dot texture across the colors, and a crisp comic-book drop shadow at a slightly tilted, playful angle. SCENE ATMOSPHERE: a starburst or atomic-orbit motif bursting behind the lettering, boomerang and jukebox accents, on a warm cream or candy-color ground. PALETTE: a saturated candy palette — cherry red, sunshine yellow, turquoise, mint, hot orange and cream — flat and cheerful, never muddy. LETTERFORM PRIORITY: when the chosen font carries its own treatment (Lichtenstein halftone, Googie diner chrome, groovy, varsity), that font treatment takes absolute priority and owns the letters; this style governs the outline, halftone, candy color, shadow and the starburst scene. FALLBACK MATERIAL: if the font carries no material of its own, render the letters with a thick black keyline outline, flat candy-color fill, a Ben-Day halftone texture and a comic drop shadow, so the retro-pop punch always reads. A mid-century retro pop poster bursting with jukebox-era energy. '八里沟夏季优惠' dominates the composition as the loud headline hero, each character wrapped in a thick black keyline outline over flat candy-color fills — cherry red on sunshine yellow, turquoise strokes on hot orange — with a Ben-Day halftone dot texture printed across every color block. A bold comic-book drop shadow angles off each character at a playful tilt, giving the text a punchy dimensional snap without any gradient or glow. Behind the lettering, a massive starburst with sharp radiating spikes explodes outward on a warm cream ground, alternating rays in cherry red and mint. Atomic-orbit rings arc loosely around the burst, dotted with small circular accent nodes. Boomerang shapes and jukebox-silhouette accents scatter at the borders — a tall jukebox outline in turquoise lower-frame, small boomerangs in hot orange flanking the text. The entire ground carries a faint Ben-Day halftone grain, keeping the surface flat and print-authentic. Palette: cherry red, sunshine yellow, turquoise, mint, hot orange, cream — saturated, cheerful, zero muddiness. Composition is dense and celebratory, pure 1960s pop-art poster energy, crisp vector-flat print aesthetic.
