For a brief period in 1971, a New Jersey based company sold novelty “x-ray” glasses through the mail via advertisements in the Marvel line of comic books. People who viewed their televisions while wearing these glasses reported seeing images that were “hellish” or “like hell”.
It should be noted that this phenomena occured whether the televisions in question were turned on or not. The company quickly went out of business and investigations reveal that the company’s address leads to a graveyard founded many decades before 1971.
