That's a good question!
I was, however, able to refer to Fred Wheaton's lost 1992 series article on it, but only after I told the person who helped me out with it that Fred worked for Topps and, therefore, the article could be trusted.
Then the same person wanted me to show him that Fred worked for Topps. So far, I can't do that, but last I looked, the reference hasn't been removed at all. It's all in the Talk page of the article if you want to check it out.
