ABSTRACT:
A removable car sign is provided for temporary installation on the inside face of the window of a car. A pneumatic bulb is placed conveniently near the driver's console. When the bulb is squeezed by the car driver it causes the sign to extend to an open position in which a message is visible from the outside of the car. When the bulb is released the sign returns to its closed position in which the message is not viewable. The message surfaces may be easily removed and replaced as one may desire.
