Concerning the WC2006 packets, there is probably a small mistake in the list between the Italian and International version. I see that 2 covers were switched.
For so far I know, the shiny packets were available in South America. For example I have a shiny vertical packet from Venezuela in my collection and I also have a box with shiny packets and horizontal backs, distributed in Venezuela, Uruguay, ...
In attachment, you can see the correction.
The printed numbers on the shiny and blue packets are the same: 000762 B04
(*) update concerning the titles:
international version (shiny) => South American version (made in Italy)
Italian version => blue packets?
international version => also blue packets but with white and black square in the corner?
South American version = (made in Brazil)
Can someone confirm if this is correct?
