Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
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.
Claim 2
Dependent Claim
88 words
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.
Claim 3
Dependent Claim
28 words
A deck of cards according to claim 1 wherein said limited range of directions is generally symmetrical with respect to a direction substantially perpendicular to said front surface.
Claim 4
Dependent Claim
58 words
A deck of cards according to claim 1 wherein a first plurality of individual cards each have holographic images appearing as a given color within said limited range of directions and wherein a second plurality of individual cards each have holographic images appearing as a color that contrast with said given color within said limited range of directions.
Claim 5
Dependent Claim
37 words
A deck of cards according to claim 1 wherein said indicia include peripheral indicia substantially confined to the peripheral margin of the respective card at diagonally opposite regions thereof and central indicia inward of said peripheral margin.
Claim 6
Dependent Claim
33 words
A deck of cards according to claim 4 wherein said holographic member is substantially coextensive with said front surface so that said peripheral indicia and said central indicia are formed by holographic images.
Claim 7
Dependent Claim
47 words
A deck of cards according to claim 4 wherein said holographic member is confined to the peripheral margin of said front surface, said holographic member having holographic images forming said peripheral indicia, and wherein said central indicia are formed to afford omnidirectional viewing of said central indicia.
Claim 8
Dependent Claim
30 words
A deck of cards according to claim 6 wherein said holographic member is formed by two substantially congruent members adapted for collocation on the peripheral margin of said front surface.
Claim 9
Dependent Claim
85 words
A deck of cards according to claim 7 wherein each of said congruent members defines a substantially L-shaped body, each said body having a relatively long leg and a relatively short leg extending perpendicularly for one end of said long leg, said short leg having an end edge remote from and parallel to said long leg and adapted to abut the said edge of the long leg of the other L-shaped body so as to be coextensive with the peripheral margin of said front surface.
Claim 10
Dependent Claim
91 words
A game piece having: (a) a game piece front surface which bears indicia related to a game activity or value; (b) a holographic member forming a first holographic image disposed on at least a portion of said front surface and constituting at least a part of said indicia; (c) said holographic member constituting means affording a substantially unimpeded view of the image in a relatively narrow and limited range of direction with respect to said front surface and to be substantially indistinguishable at directions outside of said narrow and limited range.
Claim 11
Dependent Claim
91 words
A game piece having: (a) a game piece front surface which bears indicia related to a game activity or value; (b) a holographic member forming a first holographic image disposed on at least a portion of said front surface and constituting at least a part of said indicia; (c) said holographic member constituting means affording a substantially unimpeded view of the image in a relatively narrow and limited range of direction with respect to said front surface and to be substantially indistinguishable at directions outside of said narrow and limited range.
