ABSTRACT:
The jalousie card according to the invention, includes a display card in combination with a jalousie mounted in front of the display area of the card. The display card is provided with a pair of parallel slots through which a display sheet is threaded into the display area. The jalousie includes a window frame attached to the display card, and a plurality of parallel and interconnected lamellaes that are pivotally mounted within the frame. Pull movement of the jalousie frame causes, in turn, movement of the lamellaes from a covered position about the display area of the card to an open position exposing the same, and vice versa.
