When I was a kid, I wanted this product more than anything in the whole world.
Of course, when you got it, you discovered that all the glasses could see through was your right hand. (I'll let you figure out how that worked).
So technically, the ad was "true." Of course, the real deal was:
1. it fit the goals of a pre-adolescent (power, peeping tom, magic)
2. it fit the worldview that great things were available for not a lot of money, usually by mail if you knew what to get
3. when you got it, you felt ripped off, but realized that a) you could fool your friends and b) the wait was great... you were really buying anticipation.
