Abstract
Attractive eye-catching desk-top decorations formed as flattenable pop-up cardboard structures resembling solid polyhedrons have similar polygons as top and bottom supporting panels. Foldably joined to the sides of each of these polygons are trapezoidal face panels extending diagonally outward with their longer parallel edges foldably joined to corresponding edges of mating trapezoidal face panels extending outward from the other polygon, forming an equatorial plane polygon similar to but larger than the top and bottom polygon panels. Internal glue tabs extending inward in the equatorial plane are urged toward each other by elastic bands, popping the flattened structures into their erect condition. Internal guide flanges formed by or cooperating with the glue tabs arrest and block the inward flexing movement of the trapezoidal face panels as the desired erect polyhedron shape is reached, stabilizing and rigidifying the structures to provide a prolonged useful life.
