Abstract
A laminated map or other product having a plurality of adjacent rectangular panels, formed of a paperboard sheet and a pair of transparent sheets covering the paperboard sheet, with the transparent sheets joining all of the paperboard sheets into an integrated product. The panels are arranged in at least two rows of plural panels and a plurality of columns of panels. When the pairs of panels in the columns are accordion-folded in the direction of the columns, and are then folded to cause the panels of one row to overlie the panels of the other row, the product will fold into a compact stack without substantial resistance to movement into that configuration and will be substantially flat, and when the panels are temporarily folded into single stack compact random arrays, those arrays will be compact and substantially flat. A method of making a multidirectional, multiple fold laminated product is also described.
