MAYBE YOU THINK By Joseph B

Joseph B has shown this effect to many magicians but no one has come up with a solution.
This is a powerful effect with a double ending. The magician is able to reveal the spectator's card and also the total of two dice hidden under a cup. Surprising, with a really subtle method. Joseph B in the course of the routine slowly eliminates from the mind of the spectator every possible solution leaving him speechless.

Remember: the spectator always keeps the cards face down!
