Abstract: An advertising sign arrangement for a vehicle having emergency rear doors includes a rectangular sign on each side of the vehicle mounted adjacent the top and rear end thereof. The signs on the side extend slightly rearwardly of the vehicle. A rectangular rear sign extends between the other two signs and has its upper side edges pivoted to the other signs. When the rear door is opened, it engages the rear sign and pivots it rearwardly and upwardly so that it does not interfere with the operation of the door. An elastic member extending from the back of the rear sign is engaged by the doors when they are closed to hold the sign in its downward position.
