Information display system

Claim 1

A visual display device having front and rear sides respectively for use upon a glass substrate or the like enabling simultaneous viewing of both sides of said device at any given time, including the combination of: an elongated primary member provided with two indicia display areas disposed along the length of and on the front and rear sides respectively of such primary member; a secondary member completely surrounding such primary member adjusted to coact therewith, being about half the length of said two indicia display areas of said primary member; said secondary member having indicia on each outer side and being slidably positioned relative to said primary member in order to coordinate indicia between said primary and secondary members; and a pair of abutments of a thickness greater than said secondary member, each being at opposite ends of and affixed on the rear side of said primary members; said abutments being provided with adhesive material to allow said device to be positioned upon said substrate to thereby define a clearance between the substrate and said secondary member for the free movement of such secondary member along said primary member once the display device is positioned; said abutments being fixed on said primary member to further define a maximum traverse of said secondary member along the length of said primary member for assuring the continued presence of said secondary member within the bounds defined by said abutments.
