The FBC Vacuum Sign is a medium-sized, rectangular metal plaque with a matte black finish, featuring raised, polished silver lettering that reads 'FBC Vacuum Zone'. The edges are slightly weathered, showing subtle scratches and dents indicative of its placement in a high-traffic area. The background has a faint, etched pattern resembling sound waves, aligning with the game's surreal and bureaucratic aesthetic. A small, red warning light is embedded at the top right corner, designed to glow faintly in low light, adding to the eerie atmosphere of the Federal Bureau of Control.
