the 4 different categories of goddess story 1Y, 2Y, 5Y und 10Y
To get an official goddess story box look at the boxart from the the setlists page. You can also identify them by searching for the frog logo usually on the left side of the box.
On the right side there is a number before some chinese letters. That is the prize categoy of the set. It can only be 1, 2, 5 or 10 or it is not an official box of netcent (the frog company).
