fliers
[Fliers are left on the bulletin board in the lobby and scattered on the floor on each floor of the building, including the Deluxe, Penthouse, and Roof floors. They feature plain, large font, blocky black text.]
The Phantom of the Opera is in the building. His non-fable identity is unknown. Be on your guard. 'Keep your hand at the level of your eyes.'
[There is nothing on the fliers to indicate where they came from or who made them. They are printed on plain paper, copied on a public copier at the local library.]
