Abstract
A door sign includes spaced front and rear panels with a side panel perpendicularly disposed therebetween. Both the front and rear panels each include an angularly extending slot for accommodating a door knob shaft. The side panel includes an elongated opening for receiving the door knob latch and possibly a dead bolt latch if the door is so equipped. The sign is positioned such that the door knob shafts are within the angular slots and the door knob latch is protruding through the side panel opening. If the door is closed and locked, the sign cannot be removed without unlocking and opening the door thereby preventing tampering or removal by unauthorized passers by.
