These are 2 telecartes with the 2 LOTR teaser poster visuals on it.
The retailer told me that these telecartes are released only for 2 month. They are limited and the one where Frodo is looking the Ring in his hand will be really hard to find because it was made in a smaller number.
When you look behind the cards, there is a phone number for a big contest to win a trip to New Zealand (and visit the location sets it seems) (sets? what sets? some contest! -Xo).
The phone number is: 00 33 892 700 753 (that’s when you call from the USA, in France it’s 0 892 700 753). When you call this number, you can hear the French voices of Aragorn, Frodo etc. Check out the cards here and here.
