ABSTRACT:
An incremental sheet advertising sign assembly includes a plurality of substantially identical panels to be mounted on a rail frame. Grooved wheels are attached to the back of each panel in such a manner as to engage the uppermost rail of said frame. At least one locking track is mounted vertically along the back surface of each panel, and locking elements slide along the tracks and lock the panel to a lower rail of the rail frame.
