G6
I am not completely wild about the card backs for this version (brown box), but this has a vintage charm
Concerning my copy (aqua box), and even though the card backs are generally good, a few cards are clearer and it's a problem to pull cards (because I know what cards have a back a bit clearer). Therefore I don't use this deck for this reason.
Interesting, I'll have to do a real comparison with this deck and my aqua box version. The backs and fronts, in terms of coloration, seem different. Now that I think of it, the pictures are already in this thread, but I'll need my other version in front of me to check it out. I'll look for the clarity issue you mention too.
