DISCONTINUED Ob-Ser-Vo trick - Eugene Burger
"EFFECT: The magician invites two spectators to join in a game of observation. A small packet of cards is shown to each in turn. What could be more simple? And yet, to the amusement of all the participants are unable to agree about anything - the colors, and even the quantities! Finally, the performer reveals the neither person is correct with a finish that is a delightful surprise for everyone!"
