Some question on the make up of a poker card deck:
Why 52 cards?
Why 4 suits?
Why Clubs Hearts Spades Diamonds?
What is the origin of the Ace card? What about its high/low value?
Why 2-9 but then J K Q?
2 red suits vs 2 black suits?
Origin of the Joker?
Observations:
Beveled edges
180 rotatable cards
