    摘要： A self-erecting shadow box made of paperboard, or the like, for example, for use as a display means or a greeting card, includes an open front frame behind which is positioned a foldable, rigid sheet. An elastic member is used to draw side panels of the sheet towards each other so that the central portion of the sheet is displaced rearwardly, thus creating a rearwardly extending box. When viewed from the front, the central portion of the sheet is rearward of the open frame, the side panels of the sheet converge and the bottom panel slants upwardly, thus creating an illusion of additional depth. The shadow box is initially contained within an envelope which holds it flat and when it is removed therefrom the elastic means will automatically erect the shadow box.
