| Abstract: |
A deck of playing cards wherein part or all of the indicia indicating the value of each card is formed of a holographic image which is clearly viewable from one range of angles, such as angles at or near an axis perpendicular to the surface of each card, and is obscured at other angles outside of or oblique to such range of angles. In one form the entire front surface of each playing card is formed with holographic images, and in another form only images adjacent to the periphery of each card are formed holographically. Cards constructed in accordance with the disclosure render difficult or impossible the viewing of a player's hand by persons standing or sitting near the holder.

What is claimed is:
1. A deck of game cards wherein each card has a front surface which bears indicia that distinguish the card from other cards in the deck, a planar holographic member forming a holographic image and being disposed on said front surface, said image constituting at least a part of said indicia, said holographic member being arranged to afford a substantially unimpeded view of the image in a limited range of directions with respect to said front surface and to be substantially indistinguishable at directions outside of said limited range.
