Rear window – the first commercial release from Aaron Fisher Bring out what appears to be a normal Bicycle card case. The only thing different about it is the rectangular window in the lower half of its rear face. Through this window the spectators have a clear view of the interior of the card case. With Rear Window, you can make cards visually appear inside the card case, vanish from the card case, even visually change from one card to another! For example. Remove a deck of cards from the case. Have one card selected then returned to the deck. Show the card case empty (they can see right into the window). In a wink, the selected card appears inside the card case! Remove the card from the case to verify that it is in fact the selected card. Rear Window is completely mechanical. You will love the way it works! Comes with the specially- made card case and three routines.
