Interesting fact:

Did you know that playing cards hold a lot of secrets in their images? If you look more closely at a deck of playing cards, you`ll notice 2 colours, red and black (representing day and night), 4 suits (which correspond to the four seasons), and 12 face cards (just as there are 12 months). Furthermore, the 52 cards in a deck correspond to the 52 weeks in a year. What a coincidence! Or maybe not?
