Abstract: A message display sign is provided which includes a first panel having indicia thereon and appropriately shaped and positioned windows or openings therein. A second panel is provided behind the first panel and includes a second set of indicia. When in a first position, a selected portion of the second set of indicia is visible through the openings of the first panel. The visible portion of indicia from the second panel combined with the indicia on the first panel convey a first meaningful message. When in a second position behind the first panel, a second selected portion of the second set of indicia is visible through the openings in the first panel. This second selected portion combined with the indicia on the first panel convey a second meaningful message.

Abstract: A slidable window sign is disclosed having a front panel adapted for securement to a window, a back panel attached to the front panel, and a slidable member positioned between the front and back panels. The front panel may contain indicia for viewing through the window without the risk of soiling through use. The slidable member may also include indicia and at least one protrusion thereon to allow vertical mounting without slippage. Foldable ends on the slidable member prevent it from being separated from the panels under normal uses. The ends may be unfolded to form a coplanar relation with the body of the member for purposes of removal.
