The notice boards are objects scattered around the warehouses and the back sections of the office. They usually contain warnings for the workers about the dangers in their workplace.
The notice boards have no actual purpose for the player, other than warnings about the disadvantage of disobeying the Narrator. The boards are commonly found at the Warehouse.
In the Not Stanley Ending, the distorted version of notice boards can be seen along some walls if Stanley took the right door which cause the Narrative Contradiction to the game.
