ABSTRACT:
A display device for automobiles and other vehicles alternately displays two different messages in an interesting manner calculated to attract attention. The device comprises an outer case having a plurality of spaced windows and, mounted within the case, a slide having a plurality of spaced indicia spelling out the two messages. Windows and indicia are positioned in such a manner that upon relative movement of slide and case, produced by inertial, centrifugal or gravitational forces generated by the vehicle movement, the slide alternates between two positions within the case, thereby alternately spelling out the two messages.
