<p>A changeable image display sign includes a carrier panel of corrugated board material that includes a pair of substantially planar outer walls each having an exposed major surface, and an intermediate wall interposed between the outer walls, extending along an undulating course repeatedly from one of the outer walls to the other and back, and connected to the outer walls at regions of closest approach thereto to define respective closed interstices of a predetermined cross-sectional area therewith. The carrier panel includes a plurality of openings each corresponding to a different segment of the changeable image. The sign further includes a plurality of image-forming elements of the corrugated board material, each adapted to be substantially conformingly received in one of the openings of the carrier panel and having oppositely facing first and second major surfaces visually conforming to and differing from at least one of the exposed major surfaces, respectively. A multitude of shafts each passing through respective associated ones of the interstices of the corrugated board material of the carrier member and of at least an associated one of the image-forming elements is used for mounting the image-forming elements in the openings each for turning about an axis between its active and inactive positions in which the first and the second major surface thereof is substantially flush with the one major surface of the carrier panel, respectively. <IMAGE></p> |
