Any particular reason why the Wizard of Oz Series 2 non-sport update promo (no number) is listed as "source unknown"? Was the Source not NSU?

you win!! That was this edition mystery mistake! You win nothing!

Seriously, I can not give you an answer. At one point I probably didn't know and forgot to fix it. I will make a note of it though, and I thank you for pointing it out.

I win - Seriously I would think it impossible not to find the odd mistake. At least you know I'm using it!
