This rotating message panel apparatus relates to a rigid panel that allows for printed indicia or bumper-type stickers to be placed on a vehicle in a manner that that is quickly and easily mounted or removed without marking or damaging the message panel or the vehicle. The message panel rotates to allow for viewing the message primarily from the sides when the vehicle is in motion and primarily from the rear/front when the vehicle is at rest. The controlled rotating action draws greater attention to the message. When employing bumper-type stickers, the message panel allows for changing the message as desired.
