The result is a true original, which Lehman and author Irene Clurman will discuss at the Tattered Cover on October 23. But charting your course isn't the only potential use for the cards.
"When the deck is used in a game, these cards trump the rest of the cards." Tarot cards are also used in games! I'm glad to see the media finally recognize that Tarot is also used in games. Most English speaking media reporting on tarot gives the false impression that the cards are only used in fortune telling. Tarot cards first appeared in 15th century Italy and they weren't originally called "tarot cards" The English word "trumps" is derived from "trionfi" the oldest name for the tarot deck!
Thanks for the info, grosstarock. As for future knowledge, it's all in the cards!
