I have this effect as it was part of Paul Harris’ True Astonishments package.
If you’ve
wanted to do David Blaine’s Strange Travelers but missed out buying it this is the best alternative.
In some ways it’s better - because it requires no gaff/gimmick so can be done w a borrowed deck.
You will need to learn one move - but for most intermediates and experts it will likely
already be part of their repertoire- beginners will need to practice it. Learning this move will
allow you to perform other effects so this is well worth getting if you don’t know it already.
