A card having an information portion upon which information appears that can be read in the normal manner; a portion carrying a microfilm upon which information is recorded and a portion carrying a lens suitable for reading the microfilm. The card is made from a paper card having an aperture formed in one end region in which is located the microfilm. A pair of flexible clear plastic sheets laminate opposite sides of the paper card including the microfilm. A lens aperture is formed through the clear plastic sheets and through the paper card at an end region opposite the microfilm. A round plastic lens is located in the lens aperture. The lens has a central magnifying portion and two outer annular gripping flanges that grip opposite sides of the card respectively, for securing the lens in the lens aperture. The flanges provide a rim that is higher than the maximum surface of the central magnifying portion on each side thereof for providing protection for the central magnifying portion of the lens. |
