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 placed a foldable rigid sheet. An elastic member is used to urge toward each other like portions of side panels of the sheet which are adjacent the central portion of the sheet so that the central portion is moved 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 top and bottom panels of the sheet converge or extend horizontally rearwardly, thus creating an illusion of additional depth. The shadow box is initially contained within an envelope which holds it flat. When it is removed therefrom, the elastic member automatically opens the shadow box.
