<p>The object is to make a view-changing display from one generally rectangular sheet of resilient planar material (22) having a first side and a second side. At least one viewing window (60), graspable tab (26) and slot (34) through which the tab (26) may slide are formed in the sheet (22), preferably by die cutting. The sheet (22) is divided into a front panel (62), at least one sliding panel (24) ending with a graspable tab (26), a biasing element (46) preferably comprised of a resilient panel disposed between the front panel (62) and each sliding panel (24), and an optional back panel (64) preferably extending from the front panel (62) opposite the biasing element (46). The second side of the sliding panel (24) is folded to face the second side of the biasing element (46). The second side of the front panel (62) is then folded to face the first side of the sliding panel (24) and to mate the tab (26) and slot (34). The second side of the optional back panel (64) may be folded to face the first side of the biasing element (46). The display view is changed by pulling the tab (26) which bows the biasing element (46) and displaces the sliding panel (24). This displacement of the sliding panel (24) brings a section of it that was previously covered by the front panel (62) into alignment with the viewing window (60) to display a changed view (86) comprised of printed matter, a photograph (188), any small thin object or other visible feature. When the tab (26) is released, the biasing element (46) relaxes, immediately returning the sliding panel (24) to its original position and restoring the original view (84). Multiple sliding and corresponding biasing means may be provided.</p> |
