Milton Bradley produced Kreskin's ESP, a bizarre 'board game' in which the 'players' would determine whether or not they had Extra Sensory Perception (ESP).
Kreskin's ESP comprised a series of test cards with shapes and colours that the 'players' would attempt to determine using just their minds. And if you couldn't get your ESP going with the test cards you could try swaying a pendulum with your mind to give yes/no answers to questions!
At the time Kreskin was a very popular mentalist.
