1. A collapsible stereoscopic viewer having an open top, comprising:

  • a base panel, said base panel having a rear edge, a first-side edge, a second-side edge, and a front edge;

    a rear panel for placement of at least one stereogram, said rear panel connected to said base panel along said rear edge, said rear panel having a height;

    a first side wall, said first side wall connected to said base panel along said first-side edge and connected to said rear panel, said first side wall having a first diagonal folding crease extending from a corner where said first side wall connects with said rear panel and said base panel, said first side wall having a top edge and said first diagonal folding crease terminating at the top edge of the first side wall at a termination point;

    a second side wall, said second side wall connected to said base panel along said second-side edge and connected to said rear panel, said second side wall having a second diagonal folding crease extending from a corner where said second side wall connects with said rear panel and said base panel, said second side wall having a top edge and said second diagonal folding crease terminating at the top edge of the second side wall at a termination point;

    wherein each of the first and second side walls has a plurality of different heights along their respective top edges;

    wherein each of the termination points of the first and second diagonal folding creases is positioned at a height of between 28% to 34% of the height of the rear panel when the collapsible stereoscopic viewer is in an assembled configuration;

    wherein each of the termination points of the first and second diagonal folding creases is positioned horizontally away from the rear panel at a distance of between 28% to 34% of the height of the rear panel when the collapsible stereoscopic viewer is in the assembled configuration;

    a front view panel connected to said base panel along said front edge, said front view panel detachably connected to said first side wall and said second side wall, said front view panel having two ocular lenses for viewing said at least one stereogram;

    wherein said stereoscopic viewer can be collapsed by detaching said front view panel from said first side wall and said second side wall, folding said front wall along said front edge so that said front view panel collapses against said base panel, folding said first side wall along said first diagonal folding crease so that said first side wall collapses over said front view panel, folding said second side wall along said second diagonal folding crease so that said second side wall collapses over said front view panel, and folding said rear panel along said rear edge so that said rear panel collapses over said first side wall and said second side wall;

    wherein said rear edge of said base panel is longer than said front edge of said base panel, thereby causing said first side wall and said second side wall to bend inward relative to each other in order to hold said at least one stereogram against said rear panel when said stereoscopic viewer is in its assembled configuration.
