Minimalistisches Institutionelles Zeremonie-Plakat

A minimalist ceremonial information poster for "[City Public Library Open Day]". The design is styled like a museum catalog or institutional yearbook with an abundance of warm white negative space with subtle paper texture. Strict vertical central axis alignment and structured upper-lower zoning. Top: A large, elegant thin-stroke serif title reading "[City Public Library Open Day]" with loose tracking, sharp terminals, and open counters. Center: Abstract minimalist black-line geometric symbols depicting [opened book pages and architectural door arches], flanked by two solid, hard-edged squares in [indigo blue] and [cinnabar red]. Bottom: Sparse secondary information hierarchy separated by thin black horizontal dividing rules, displaying concise subtitles, event dates, and micro-text footer details near the lower edge. Style: Restrained Swiss-style graphic design, high contrast, flat colors, no drop shadows, no gradients, no photorealistic elements.
