  • Patent number: 3946508
    Abstract: A display card of the pull card type having a swinging operating tab for sliding an intermediate display leaf between a back leaf and the display aperture of a front display leaf to shift the intermediate display leaf and change the scene or message visible through the display aperture. The front and back leaves are joined at their sides by folds which provide an envelope for the sliding intermediate leaf and which also serve as relatively long guides for the sliding intermediate leaf; and the tab has two spaced hinge-like folds, one connecting one of the two layers of the tab to the intermediate leaf and the other fold connecting its other layer to a flexible projecting section of the back leaf. The two ends of the envelope are open and the intermediate leaf may be elongated to extend beyond the end of the envelope when the tab is in the folded position.
