Abstract

Abstract Forming a calendar by a unique manner of cutting and folding a material into a geometric form having adhesive faces and which may be unfolded to show various successive surfaces having dates or advertising material thereon. As the geometric form is unfolded to show a new date that surface formerly showing the date or descriptive material may be adhered to the wall or surface to which the calendar is mounted. On the back surface of each folded dated surface or advertising surface there appears a fragmented portion of an overall pictorial representation so that when the calendar is completely unfolded and the formerly exposed surfaces are adhered to the wall there will be shown a pictorial representation in its completed form, which is comprised of all the back surfaces.
