Use the image I've attached. Turn it into an event poster in the Swiss International Typographic Style of the 1950s and 60s, keeping the photo's subject, pose and composition recognizable. If there are people in it, keep them looking exactly like themselves. Design: the photo converted to high-contrast black and white and cropped boldly on a strict modular grid; one flat accent color, a strong red, used for a single block or shape; a clean neo-grotesque sans serif, set flush left and ragged right, with tight but legible spacing; the title "{{event_name}}" set large and bold, and the date "{{event_date}}" set small on the same grid; generous white space and precise alignment, so every element lines up with the grid. Objective, calm and orderly, printed flat on bright white paper. Spell the text exactly as written, and add no other words, logos or watermarks. Format: portrait poster, 2:3.
