A fantastic effect, now supplied with special original Bicycle poker size cards!

The magician shows a small wallet that has two cards clearly visible inside: a 7 of Clubs, and a 7 of Diamonds. He takes out the 7 of Diamonds, and puts it face up on the table. He then takes the 7 of clubs and puts it face down onto the first card. A magical gesture, and the printed face of the 7 of Clubs disappears leaving the card blank, and ends up... on the back of the 7 of Diamonds!

• The cards are poker size. The wallet measures cm 7.7 (3") x 10.5 (4.1").
• The trick is self-working, no manipulation is required and the secret is really ingenious.
