Hmm, I found this: http://pocketmedia.ign.com/media/news/image/otherstuff/yellowcountries.jpg
Checking other pictures about Yellow, it proves the picture above true, so it's either seal or rating, depending on the version.
Okay, Yellow seems good enough. What about the others?
And anything else you notice, like, the quality of the stickers, or something?

There seem to be round ones too.
Edit 2: You are right about the font, though I see many pictures on original Crystal cartridges too. Odd.
If one is fake and the rest are suspicious, I don't think why the others would be any different. The rating is not white, but black on the Yellow version as well. They are definitely fake, it seems. I won't buy them then, thanks a lot.
Now I have a GBC and a magnifier+light, but no game into it o_o
And on ebay no original deals I found ship to Europe. FML. I'd be thankful if someone helped me find a deal :l
I spent hours looking for a damn GenII cartridge -_-
