Space Mountain... Steampunk?

Apparently Disneyland in Paris has made a variety of pretty and old-fashioned posters. I stumbled across them here. I am struck by this poster of Space Mountain. It may be a totally modern thing, but it is pretty and sort of Steampunk looking to me. Let me once again point out where this is... Paris. As in French. I keep saying that Steampunk is French... they don't even have to do it on purpose, it just happens!
