This Milton Bradley outfit, copyright 1967, tapped the popularity of the Amazing Kreskin, who once had his own television show. Born George Joseph Kresge Jr., in 1935, Kreskin performed as a "mentalist." (As distinguished from a psychic, a mentalist uses magic tricks and/or simple principles to demonstrate apparent "mind reading" and similar phenomena for entertainment purposes.)
This set contains (in a box about 9½ x 19 x 1¾ " high) two kinds of ESP test cards; symbol cards (not the standard Zener cards) and color cards; a cardboard "ESP Test Screen" (to keep card from test subject's view); a "Mystery Pendulum" (which works by involuntary muscular movement, as do Ouija boards and dowsing rods); pendulum subject's cards; folding game board; and instruction booklets.
Unfortunately, the kit offers no real skepticism about the existence of ESP, instead referring to the cards and pendulum as "two scientifically proven ways" to "explore the outer frontiers of the human mind."
