From a pile of 12 cards each bearing one of the 12 star signs, a spectator removes theirs and it is slipped unseen by the performer into an envelope which is left in view.
12 further cards, which bear descriptive character trait words for each of the star signs, are shuffled and three selected by spectators at random.
The performer takes the three cards and tries to assess whether the words on any of them appear to apply to the first spectator. He eventually decides on one card. On removing the star sign card from the envelope it is seen to match!
