Abstract: A display device having a collapsible display board which removably receives pictures which are intended to be displayed. The display board can have affixed to its back a support receiving means, the receiving means further being collapsible. In one mode the receiving means receives a supporting pole member which is itself supported by a polyhedral base such that a free standing display board is formed. The polyhedral base is collapsible into a substantially flat configuration for storage. In a second configuration, the support receiving means receives an L-shaped supporting bracket which can support the display board in its display mode on a flat surface such as a countertop or desk. This bracket is further collapsible for storage. Thus, by utilizing either of the supporting structures, the display board can be supported in either the free standing mode above the polyhedral base or can be adapted for mounting on a countertop display surface.

Abstract: A collapsible, self-erecting pentagonal dodecahedron hollow structure formed from two integral blanks of paperboard, each of which is cut and scored to form a central pentagonal having integrally formed therewith five other generally pentagonal walls which are affixed to the respective ones of the edges of the central pentagonal by a score line. Each of the generally pentagonal walls has a triangular flap which is hingedly affixed by means of a score line along one of its edges so as to be disposed between adjacent ones of the pentagonal walls. A slide member is affixed to each of the triangular flaps and is disposed to extend beneath the adjacent pentagonal wall. Each of the pentagonal walls of one of the blanks has a foldable attachment flap affixed by a score line to the outwardmost edge thereof. Each of the pentagonal walls of the other one of the blanks has a foldable hook flap affixed by a score line to the outwardmost edge thereof.

Abstract: A collapsible, self-erecting hollow structure which is formed from an integral blank of paperboard which is cut and scored to form a plurality of side and end walls which when erected form the hollow structure. Each of the plurality of side and end walls are hingedly connected along one edge thereof with at least one other wall. The hollow structure also has at least two flaps, each of which is hingedly connected along one edge thereof with at least one of the plurality of side walls. These flaps each is cut and scored to form an attachment and further is folded and affixed to one of the plurality of end walls on the side thereof which is interior of the erected hollow structure. An elastic means such as a rubber band is secured under tension to the attachments and normally pulls the two end walls to which the flaps are hingedly connected toward one another and thereby erecting said hollow structure. The hollow structure may also have affixed to it a copy extender.

Abstract: A three dimensional internally illuminated advertising device is sized the same as the panels forming a suspended ceiling and is used in place of one of the panels and is supported by the suspended ceiling grid network.
