发明名称 Progressive display card
摘要 This invention relates to a novelty item which may be used as an active greeting card or a promotional advertising display device. The card itself contains a number of display leafs which are progressively "turned" by pulling a pull tab in the card base. The pages may have a "pop-up" action device mounted between each pair of leafs to give a 3-D effect as the leafs are progressively turned.
