Abstract
A folded stationery piece has a three-dimensional pop-up message displayed along an internal fold line, formed by an arrayed sequence of letters with the spaces between them removed. The letters and bridge webs joined to their upper edges are both hinged to the stationery panels, forming a collapsible parallelogram structure. The message display can be formed as a separate insert, to be adhesively mounted along a fold line of any piece of stationery by the user.
