The FBC Poison Sign is a stark, rectangular metal plaque with sharp, clean edges, embodying the brutalist aesthetic of the Federal Bureau of Control. Its surface is slightly weathered, featuring a matte black finish with raised, glossy red symbols that glow faintly in low light, warning of toxic hazards. The sign's design is minimal yet ominous, with the poison symbol centrally embossed and surrounded by angular, geometric patterns that hint at its surreal, otherworldly origin.
