Mathew Knight's Invisible Date- Trick

All the power of an Invisible Deck with a personal connection with your audience! Have a deck of cards in full view that contains two very special Jokers. They are not only special because of being face down in a face up deck, but also containing a personal information of the spectator on their faces. Let the spectator name any date of the year, may it be his birthdate, his wedding date or the date of his divorce. Slowly spread through the face up deck, just to reveal what you promised: two face down cards; the two Jokers, and exactly showing the date that the spectator selected. Works in any language, as you can prepare the deck in your handwriting and mother language. Comes with English video instructions.
