In 1910 at a séance in Grenoble, France the apport medium Charles Bailey produced two live birds in the séance room. Bailey was unaware that the dealer he had bought the birds from was present in the séance and he was exposed as a fraud. The psychical researcher Eric Dingwall observed the medium Bert Reese in New York and claimed to have discovered his billet reading tricks. The most detailed account at exposing his tricks (with diagrams) was by the magician Theodore Annemann.
Like common playing cards, the tarot has four suits (which vary by region: French suits in Northern Europe, Latin suits in Southern Europe, and German suits in Central Europe). Each suit has 14 cards, ten pip cards numbering from one (or Ace) to ten and four face cards (King, Queen, Knight, and Jack/Knave). In addition, the tarot has a separate 21-card trump suit and a single card known as the Fool. Depending on the game, the Fool may act as the top trump or may be played to avoid following suit. These tarot cards, without occult symbology, are still used throughout much of Europe to play card games.
