ABSTRACT:
This display advertisement qualifies for second-class postal rates because it is all one piece of paper when bound into a publication, when mailed, and when received by a recipient of the publication. Yet it is capable of operation by the recipient to display two or more different images. One area of the sheet forms a slidable-panel portion for motion, eventually, within (or behind) other portions; this slidable-panel portion is folded over to lie within (or behind) the other portions, and connected to the other portions by a perforated tab. The tab initially restrains the slidable-panel portion against actually sliding. The recipient breaks the tab to free the slidable-panel portion, making it actually slidable; and then moves the tab to slide the slidable panel. Preferably the other portions of the sheet are folded and glued to form a flat tube that is tipped (or otherwise bound) into the publication. Parts of images--including photos, lettering, etc.--are formed on upward-facing surfaces of both the top and bottom (i.e., interior) of the tube or of the slidable panel, or preferably of both; and windows are defined in the flat tube--and if desired in the sliding panel as well--to reveal only selected parts of the images, depending upon the position of the sliding panel.
