The FBC No Entry Sign is a medium-sized, rectangular metal sign with sharp, clean edges, embodying the brutalist architecture style of the game. It features a bold, black 'NO ENTRY' text on a bright red background, with the FBC logo prominently displayed at the top. The sign's surface is slightly weathered, showing minor scratches and dents, suggesting it has been in place for some time within the Bureau's surreal environment. The back of the sign includes mounting brackets, indicating it's designed to be affixed to walls or doors.
