Color I Do As U (Abbott Magic Co.)......$6.00

Created by George Boston the effect is as follows:  The performer
exhibits two decks of cards, one red, the other blue.  He picks up
one deck and shows it to be quite ordinary, both back and front.  
He asks a spectator to assist by placing the deck behind their
back and cutting it any number of times, completing the cut each
time, then to remove two or three cards from the deck and then
place them in their pocket without looking at them.

The performer then requests the spectator to square the pack and
bring it from behind their back held in such a manner so that the
performer cannot get a glimpse of any card.  This deck is then
placed back into its case and put aside.

Performer takes the other deck from the table and shows that both
the back and front are quite ordinary except that the backs are a
different color from the first deck.  This is to convince the audience
that only two decks are used, one by the spectator and one by the
performer.

The performer then places this deck behind his back.  He cuts his
deck the same number of times as the spectator cut their deck
and then removes the same number of cards from his deck as the
spectator did from their deck and then discards his deck as well.

The spectator then shows their selected cards, one by one, and
the performer shows his in the same manner.  The audience is
amazed to find that the performer has matched the spectator's
cards with his own!  Truly a miracle, because neither one has
looked at any of the cards while the trick was in progress!
