Claims
- 1. A display, comprising:
- a sign for advertising and displaying information;
- said sign having a billboard comprising a substantially planar and rectangular stationary rearward web, a substantially stationary front web spaced in front of and substantially parallel to said rearward web, a frame assembly having a front frame section with substantially horizontal top and bottom beams fixedly secured to said front web, and at least one upright post connected to said bottom beam for elevating said webs above the ground;
- said rearward web having first and second superimposed striped images thereon;
- said front web comprising a substantially transparent viewable portion with a set of aliquot slit-like spaces providing a series of substantially rectangular transparent windows for viewing only said first superimposed images from first angular position and for viewing only said second superimposed images from a second angular position, and said grid-like pattern comprising a set of aliquot spaced opaque bars with substantially rectangular portions positioned between said rectangular windows for substantially blocking the view of said second superimposed image from said first angular position and for substantially blocking the view of said first superimposed image from said second angular position;
- said first superimposed image on said rearward web having viewable first opaque portions and substantially rectangular obstructed invisible first spacer portions, said viewable first opaque portions comprising an array of aliquot spaced substantially rectangular first strips with first indicia thereon comprising some of said information, said first strips having a width less than said windows and being aligned in registration with said windows for viewing in said first angular position, and said first spacer portions spanning a width less than said bars and being substantially obstructed and blocked from view by said bars in said first angular position;
- said second superimposed image on said rearward web having viewable second opaque portions and substantially rectangular obstructed second spacer portions, said viewable second opaque portions comprising an array of aliquot spaced substantially rectangular second strips with second indicia thereon comprising some of said information, said second strips having a width less than said windows and being aligned in registration with said windows for viewing in said second angular position, and said second spacer portions spanning a width less than said bars and being substantially obstructed and blocked from view by said bars in said second angular position; and
- at least a portion said first opaque strips of said first superimposed image being positioned in at least a part of said second spacer portions of said second superimposed image on said rearward web, and at least a part of said second opaque strips of said second superimposed image being positioned in said at least a part of said first spacer portions of said first superimposed image or said rearward web.
- 2. A display in accordance with claim 1 wherein:
- said frame assembly comprises
- a substantially rectangular front frame peripherally surrounding and connected to said front web,
- a substantially rectangular rearward frame peripherally surrounding and connected to said rearward web, and
- upright side walls providing connecting members for conecting said front and rearward frames; and
- the relationship of the width of the bars of the grid, the width of the stripes of the superimposed images, and the spacing between the front web and the rearward web, to a focal point of an observer, are in accordance with the following formulas:
- S=B-D and
- A/B=C/D
- wherein
- S=the spacing between the front web and the rearward web
- B=the distance between the rearward web and a focal point of the observer
- D=the distance between the front web and the focal point of the observer
- A=maximum width of any stripe of the images
- C=maximum width of any bar of the grid.
- 3. A display, comprising:
- an educational game for displaying information;
- said educational game comprising a substantially planar and rectangular stationary front web, a substantially rectangular frame assembly providing a housing surrounding and fixedly secured to said front web, a flexible moveable rearward web spaced rearwardly and below said front web within the interior of said housing, and a scroll assembly operatively connected to said housing for rotatively moving said rearward web;
- said frame assembly having substantially rectangular front wall portions peripherally connected to and positioned about said stationary front web, a back wall, and transverse walls extending between and connected to said back wall and said front wall portions;
- said scroll assembly comprising elongated substantially cylindrical rollers operatively positioned in said housing, said rollers including a lead roller rotatively connected to said rearward web for rotatively moving, advancing, and winding said moveable rearward web in one direction and a trailing roller positioned substantially parallel to said lead roller for rotatively moving, retracting, and cranking said moveable rearward web in an opposite direction, a lead advance mechanism operatively connected to said lead roller for rotating said lead roller, a trailing mechanism operatively connected to said trailing roller for rotating said trailing roller, said mechanism comprising a manually grippable handle selected from the group consisting of a crank and a knob;
- said rearward web having first and second superimposed striped images thereon;
- said front web comprising a substantially transparent viewable portion with a set of aliquot slit-like spaces providing a series of substantially rectangular transparent windows for viewing only said first superimposed images from first angular position and for viewing only said second superimposed images from a second angular position, and said grid-like pattern comprising a set of aliquot spaced opaque bars with substantially rectangular portions positioned between said rectangular windows for substantially blocking the view of said second superimposed image from said first angular position and for substantially blocking the view of said first superimposed image from said second angular position;
- said first superimposed image on said rearward web having viewable first opaque portions and substantially rectangular obstructed invisible first spacer portions, said viewable first opaque portions comprising an array of aliquot spaced substantially rectangular first strips with first indicia thereon comprising some of said information, said first strips having a width less than said windows and being aligned in registration with said windows for viewing in said first angular position, and said first spacer portions spanning a width less than said bars and being substantially obstructed and blocked from view by said bars in said first angular position;
- said second superimposed image on said rearward web having viewable second opaque portions and substantially rectangular obstructed second spacer portions, said viewable second opaque portions comprising an array of aliquot spaced substantially rectangular second strips with second indicia thereon comprising some of said information, said second strips having a width less than said windows and being aligned in registration with said windows for viewing in said second angular position, and said second spacer portions spanning a width less than said bars and being substantially obstructed and blocked from view by said bars in said second angular position; and
- at least a portion said first opaque strips of said first superimposed image being positioned in at least a part of said second spacer portions of said second superimposed image on said rearward web, and at least a part of said second opaque strips of said second superimposed image being positioned in said at least a part of said first spacer portions of said first superimposed image or said rearward web.
- 4. A display in accordance with claim 3 including a
- removable cassette for substantially containing said rollers and said rearward web; and
- said housing defines a slot for slidably receiving said cassette.
