Pop-up items are provided which can either be mounted in three-dimensional form on a suitable supporting surface by means of pressure-sensitive adhesive carried by the item or can be affixed to facing panels of a letter or pages of a book. Some preferred items include a pop-up element in the form of one or two panels carrying strategically located pressure-sensitive adhesive which permits instant mounting, e.g. between facing panels so that, upon opening, the pop-up element assumes a three-dimensional configuration as a result of the pressure-sensitive adhesive bonding to the surfaces of facing panels or pages. The 3-dimensional pop-up can also be mounted to a suitable supporting surface. A variety of methods for the mass production of such pop-up elements from a continuous web, e.g., a printed and die-cut web from a web press, facilitate their inexpensive fabrication. These pop-up elements are preferably marketed or distributed in groups, e.g. defined by perforations within a surrounding matrix, or attached to a continuous strip of carrier sheet material that might be rolled or fan-folded, or in the form of stacks or pads from which a single item can be peeled off and affixed. Sheets containing multiple, single-thickness pop-up elements in blank form are specially adapted for customized printing by electronic imaging.
