Abstract
This disclosure is concerned with a readily changeable sign display system which facilitates easy alteration of the sign indicia displayed but is also resistant to unauthorized tampering so that it can be deployed where it is not under continuous surveillance when exposed to the general public. It comprises vertical frame members which provide tracks for the insertion of horizontal frame members. In some embodiments the vertical frame members are joined to each other with a backing member while in other embodiments intermediate channel members are placed between the vertical frame members and adjacent members are joined by a backing member. The horizontal frame members carry grooves for the insertion of sign panels which carry indicia. The tracks for the horizontal frame members carry removable obstructions which hold these members in the tracks. The obstructions at the upper end of the tracks are readily removable.
