I use the Lenny rule, if I never seen Lenny selling it I consider it something someone faked/altered when it comes to the Ripken card.
Like you I remember the article on the white box but I have never actually seen one. What do you mean by aftermarket? I have never seen a whiteout that I believe someone didn't make at home but as far as I know all the scribble versions are 100% factory printed.
I am far from an 89 Fleer error/variation expert but I have owned a couple.
