Abstract
A self-erecting pop-up stationery display structure assembly bonded to an underlying stationery sheet supports a display panel positioned overlying the stationery sheet. The collapsible self-erecting support has a central panel spanning the space between the stationery sheet and the overlying display panel, with first and second end panels joined to it by respective first and second fold lines, the first being formed of resilient elastomer leaf spring sheet material with a preformed angular bend formed therein. A collapsing force causes the central panel to fold toward the stationery sheet, elastically deforming the preformed angular bend in the resilient elastomer sheet. Removal of the collapsing force releases the deformed angular bend, which returns elastically to its preformed bend configuration, positioning the display panel in a deployed position spaced from the stationery panel.
