I found this "Easy Play Instructions" sheet inside an NES Fun House box. 
Almost twice as long as the NES box on thick paper it comes folded in half. 
Did a little searching and didn't see anything about this company. 
Any others like this turn up in the past?

There have to more of these out there but it is a hard string of words to search for.

Interesting. I remember Funcoland having one-sheet instruction cards they included with some 16 bit games, printed on stiff colored paper. It's possible this was a similar effort by a retailer. Surprised there isn't more info, however. Have you tried tracking down the company in some kind of registry?
