Yeah the numbers are printed and not in hub area.
So yours could be a good knock off and one would never know- no country of manufacture?
Hmmm... not sure where you're coming from here. Couldn't anything you buy from ebay be a knockoff? But isn't some of it legit?
Where are you expecting one to find the country of manufacture?
Here is what I can tell you: my disc appears to be pressed, is well-printed and plays flawlessly. It contains the number I cited printed on the disc and in the credits at the bottom back of the sleeve. It contains your number in the upper left of the rear of the sleeve.
Could it be that there is a number for the disc and a number for the box set? Or something like that?
