Create a finished 3:4 vertical event flyer for an art exhibition, with exact rendered text: small top eyebrow: “ONE NIGHT ONLY” main headline, two lines: “BLACK” / “& BLUE” subhead: “AN ART SHOW” detail line: “FRIDAY, SEPTEMBER 18, 2026 · 7–10 PM” venue line: “NORTHLINE PROJECT SPACE · 118 CANAL STREET” footer: “OPENING RECEPTION · FREE ENTRY” Composition: an assertive mid-century print poster with a flat saturated electric-blue ground and a deep near-black vertical panel occupying the left 28% of the page. Center the headline across the boundary, filling 70% of the poster height. “BLACK” sits upper-middle; “& BLUE” sits directly beneath, tightly stacked. Set the headline in custom wide, heavy retro slab-serif display lettering: uniform thick strokes, thick square slab serifs wider than the stems, broad sturdy proportions, slightly compressed tracking, soft pressure-impressed letterpress edges and subtle ink spread. The BLACK letter faces are electric blue with a deep near-black offset shadow shifted 10 px down-right; BLUE letter faces are near-black with an electric-blue offset shadow shifted 10 px down-right. Apply a clearly visible, evenly spaced halftone screen-dot field inside the dominant electric-blue letter faces; retain crisp, hard-edged contours. Place “ONE NIGHT ONLY” in small near-black slab capitals at top right. Set “AN ART SHOW” in black slab capitals beneath the title, aligned to its left edge. The date, time and venue sit as two compact blue-on-black bands in the lower quarter, then the footer in small near-black capitals at bottom right. Add only graphic print elements: an oversized cropped blue halftone circle in the top-left, a black sunburst of 12 blunt rays behind the ampersand, and two tiny blue registration-cross marks near the bottom corners. Flat two-color ink, no gradients, no photographic objects, no paper mockup, no devices. Crisp screenprint geometry, high contrast, clean margins, readable hierarchy.
