Abstract
A durable lightweight rigid transparent envelope that is slightly curved in shape from top to bottom and attaches to automobile windows via suction cups in order to hold and display a variety of double-sided thin flexible lightweight message sheets, which are highly color-contrasted, light-reflective and contain large font character size messages in order to facilitate visual communication between automobile operators, passengers and pedestrians at distances normally encountered on streets and highways. A selected message can be displayed in the envelope through the envelope's transparent front side when it is attached to the inside of an automobile window, or a selected message can be displayed through the envelope's transparent back side while the envelope is attached to the outside of an automobile window by the same means. Indentations at the top of the envelope provide for quick and easy removal of message sheets by grasping them with the tip of a thumb and finger of the hand Small notches at the top of the envelope provide for the attachment of elastic bands in order to hold the message sheets in place inside the envelope when laying flat while not in use or being stored
