OSC Studio designed the key visual and poster system for Afterimages of Peace, the 2026 Public Art Project in and around the Peace Culture Bunker. The observation tower—a symbolic structure of the site—was selected as the central motif to communicate the location’s identity. Vivid colors and glass-like effects of refraction, layering, and distortion visualize the idea of an “afterimage.” The design represents how the site’s accumulated historical and cultural traces intersect with the diverse perspectives of participating artists, transforming them into a new cultural and artistic landscape. The resulting visual system was designed to extend consistently across posters, banners, signage, and other promotional materials.
