This is now a common occurrence I fear when dealing with modern posters and sellers using digital images they find on the net as opposed to photographing the actual item - especially as the myriad International versions will all have different dates on them.
If one is intent on collecting all versions, it will mean buyers will have to diligently question every single seller and ask them to photograph the item, or rely on some cursory glanced description that they feel will be all is necessary.
As well as the potential for an incorrect image, there will also be confusion as to the actual existence of some images bearing in mind the profusion of none papered digital-only versions.
Good luck. (I will have to go through all this again come the release of SPECTRE posters - poor me,
)
