The Darjeeling Limited (2007)

[scorsese1]

Does anybody else have a copy of the Darjeeling Criterion blu-ray with back cover art different to the back cover pictured on this site? In place of the plain blue art pictured here, mine actually has a further illustration of the train cars winding around a bridge and a man is sitting on top of the train with a green shirt seen from behind. Everything else about my disc is the same(features,front cover,etc). I just noticed this recently and have not seen another copy in stores for comparison. I got my copy in early 2011, so it's not from a recent printing that may have had some kind of cover art change. Just wondering if anybody knows what might be going on here.
