How to Spot Marked Cards

• Any complex back design may be marked. One of the only two ink colors--navy blue or medium red--will suffice for the well-known U.S. Playing Card brands. The trouble with marking cards at home, however, is that the deck's seal must be broken.

• Premarked cards, favored by serious players, come from Lous Tannen, Inc., a New York magic supply house. Tannen's marked decks are genuine U.S. Playing Card decks that have been opened, marked by hand, and resealed with a duplicate U.S. Playing Card stamp, cellophane wrap, and a white tear-band bearing the brand name.

• Each deck comes with separate instructions for decoding the markings. Big Secrets ordered Tannen's Aviator, Bee, and Bicycle decks to see how the markings are concealed. So if you come to our company, professional persons will tell you how to make it. And you can gamble at poker games. It looks very funny.
