New ESP Test Cards by Full52
The five familiar geometric shapes have been expanded to ten and abstractified, giving a much wider and more diverse range of choices. And, the plain old black and white cards have been blown away by an explosion of colour!
The 'New ESP Test Cards' is a very unique, marked deck of cards that allows you, the operator, to know FIVE different pieces of information on the face of the cards simply by reading ONE number from the back.
Believe it or not, all you need to be able to do is COUNT TO TEN!
