Abstract: An expandable card form is described that includes a plurality of foldable leafs that are foldable onto one another at fold lines which separate each adjacent pair of foldable leafs. A slot can be cut through the fold line separating one of the adjacent pairs of foldable leafs. The plurality of foldable leafs can be connected to one another linearly and can include adhesive sections so that, when assembled, the foldable leafs form an expandable card. One end leaf can include a projecting panel attached thereto. The projecting panel can be extended through the slot when the card is expanded and can be retracted so as not to be visible when the card is oriented into its closed configuration. The expandable card can include information printed thereon to create a business card, a place setting card, a medical information card, or a gift card.
