ABSTRACT:
A sign wherein individual film panels bearing graphical information are interconnected as an uninterrupted web by way of interconnecting plastic zippers. The web, which is composed of a series of film panel transparencies, is wound and unwound from spaced apart rollers for presenting the individual panels for viewing through a window in a housing. The concept of releasably interconnecting film panels is also used in stationary signs such as menu boards in fast food restaurants to provide for easy interchange of the panels when it is desired to present different menu items and prices, for example.
