THE MARK TWAIN BOOK TEST allows you many different ways to read your participant's mind. Use both books in tandem with each other or use them separately.  HUCK FINN is gimmicked as well and can be examined briefly and pass as a normal book. The Autobiography reads like a normal book and is gimmicked in a familiar way. You can also use another regular book with THE MARK TWAIN BOOK TEST or even use another book test with it! INCLUDES: PDF and Video instruction.
