Desired State by Jim Kleefeld
Have someone choose one of the 50 states in the U.S. for an imaginary visit. Let them name their state mixed in with a dozen other states. You always know which one is their chosen state. Incredibly easy to do, yet mind-bogglingly baffling. The props include postcards, but this is NOT Classic Film Verite - it works on a different principle, so you will fool everyone, even "those in the know."
Includes 50 vintage state postcards and full instructions.
