I'm not sure if any of you guys have seen these but here is a collection of the limited edition Star Wars posters mondo released.Poster collectionHere is the Mondo Website
My personal favourite is this
Sadly I've never been able to get the posters. They're released at a random time so everybody has a fair chance of getting one and are limited to a small number. Also they cost a lot of money.
They have done many other posters from other films so I recommend you check out their blog and see. Be prepared to get your geek on because they're awesome!
