But I am not sure they are original? What is a "vinyl" poster?
If it's 27 x 40 and vinyl, I suspect it's not original. There is a large vinyl banner version as Rich mentions (prob around 8ft x 5ft)
Whilst browsing ebay, I have seen the following 27 x 40 posters:
- US one sheet, double sided, August 22nd release date on the poster
- UK one sheet, single sided, August 25th release date on the poster
- International/Asian region one sheet, double sided, no release date and logos on slightly different position
