I got this when I was a kid, I remember it came in the mail with a book. My dad signed up for every game mailing list, I remember also getting stuff from Squaresoft . We ended up buying both Ninja Gaiden games through this since I liked the book, which I definitely still have somewhere in my attic. I don't think this was the only one we got, maybe one more because we also got a free Blaster Master book. I'm gonna ask my dad and my brother and see if they remember anything more.
