What the heck is going on with the label notes?
I caught that too, but you beat me to it.
Yes, I pointed out this problem to CGC by sending a scan. Unfortunately, in order to get this corrected, I'm going to need to send it in. They said that I wouldn't be charged for correcting the problem, but I believe that I'm going to end up paying for shipping. Since it is their mistake, it seems like they should ship it back to me on their dime, but we'll see.
It appears that CGC entered the book into the database as the X-Men 1991 series. I checked the census and there is a 9.2 entered into the census in issue #59
census for issue #59, X-Men 1991
