Thanks for your answer.
To summarize :
On rollingstones.com, you can buy the "Book pack" which include 6 cards (90 euros with postal to France).
On Amazon, you only have 4 cards but it cost 48 euros with Postal to France. Forum: Buy/Sell/Trade
I bought this new box on Amazon. Great box, beautiful work. I found 4 art cards on this box (as describe on the box) but it seems that you can find box with 6 art cards. Do you have more information ? Forum: Buy/Sell/Trade
