A portrait A1 conference poster in strict Swiss International Style for a fictional design conference. White background. A precise modular 12-column grid is implied but invisible. In the upper third, a single solid red circle aligned to the right margin, exactly 18% of the poster width. Diagonally crossing the lower two-thirds of the poster, a thin black baseline at exactly 23 degrees carries the conference title "FORM AND FORM" in lowercase Helvetica-like neo-grotesque, rotated to align with the line, set in black, perfectly kerned. Above the baseline, a small block of left-aligned metadata sits flush to the grid: "05 — 07 MAY · ZÜRICH HOCHSCHULE · TYPE / SYSTEMS / TOOLS". Below the baseline, a four-line speaker list in 9pt, names only, separated by middle dots. Footer carries two minuscule sponsor wordmarks aligned to the bottom grid line. No images, no gradients, no shadows. Just type, geometry, white space, and one red dot.
