This is a quote from the opening text of the instructions. It will give you some idea of what it's about.
"The King Size ESP Cards make possible an endless variety of new and startling mental routines that will be accepted as real mental miracles.
Because of the widespread publicity and scientific acceptance of the ESP experiments, any and all of these effects should have a definite impact on the audience. Their large size makes them adaptable to club and platform work.
Because only five different designs are employed, the actual modus operandi of this series of ESP Brain Busters is simply amazing."Price $10
