Make Others Secretly
Do Your Bidding

It is too bad that this ad is so hard to read but let me sum it up for you. According to the ad, there are three simple steps to getting started with mind control.

1) Send in your money.

2) Open the package.

3) Let the secret "feed itself into your mind automatically."

After that it was a simple matter to get free money or to summon distant friends and pretty much rule the world all for only $10.98.
