Ronjo Magician's Insurance Policy - 3 1/2 Clubs

When the magician fails to find a chosen card, he whips out his insurance policy, reads out loud the terms of the policy (jokes printed inside).

The policy only covers half. Half the card. The selected card was the 7 of Clubs. Open the policy once more to reveal a large  poster of the 3 1/2 of Clubs.
