Oui c'est ça je viens de voir qu'il y avait une autre photo avec la n'explanation.
place the full animal card head downward in the left hand, cover this card with the jack of clubs, spade and hearts, also with animal head downward, place yhe jack of diamond on top draw cards to the right in a fan-like shape keeping the full animal card covered with the jack of clubs, making it appear as if the bearer only had four cards in hand.
Now push the cards back in their former position, still having the jack od diamonds as your upper card.
Place this jack of diamonds at the bottom of the deck, removing the animal card to the top of the deck, turn the deck of card so as to bring the animals heads to the top, now open yours cards to the right in a fan-like shape, still having the last card covered-wich is no the jack of diamonds.
To your surprise you will now see that that your four cards consist of animal heads.
