Disneyland Paris has a bunch of beautifully designed attraction posters.
Here are a few nice examples.

Unfortunately they are not being sold in the parks, although Disneyland is already offering its classic posters as minature prints.

Well,... merchandising at DLP never really was the best...


Please note:
These posters are not for sale at the TSOM. All posters (c) Disney-WDI.
To purchase attraction "atmosphere" posters please visit the posterstore.

To view the posters, please click on the round image.
The poster will open in a new window.
All posters are 567px high.
