Parade Of Four

NOTE:  This is used.  In good condition. 
It came from a magician's estate.  

Four cards in a small envelope.  The magician says they are the four 4's and ask someone to name a suit - Heart, Club, Diamond or Spade. 
Whichever suit they name, the cards are removed and shown to be face down except for the selected suit.  That is face up.  When it is removed from the fan of cards, it has a different color back! 

Includes instructions.
