ABSTRACT:
A pop-up device for a card, book, novelty, or the like has a sandwich-like structure including a base or back (300), a front or cover (200), and a tongue (130) disposed between. All three sections may be of equal length. The three sections are folded onto one another and glued to make the sandwich. The tongue has a protruding tab end (135) for a user to pull; the end distal the tab end is fastened to a portion of the cover. A pull-slot (325) cut out between the cover and back guides the tongue for pulling to eliminate shims. The cover is slit by two parallel cuts (210) and three crosswise creases. The cuts are parallel to the tongue. The creased portion of the cover pops up when the tongue is pulled by a user. The fold lines are perpendicular to the direction of the tongue movement.
