Interesting Vacation one sheet

[kovacs01]

I was the underbidder on this one on emovieposter.com's tuesday night auction.  Now that its over, I figure I can ask folks' opinion on it.  That its the same art but missing title and credits, etc leads me to believe this is some sort of preposter.  Those are often smaller and on cardstock, but this one is the normal 27x41 size.  Since it is for the first Vacation movie and not a sequel, I cant really believe that this was ever intended for advertising use without any text at all on it.  I guess it could be a commercial print, but the size suggests otherwise.  What do you guys think?

I was watching that one as well, I was thinking a proof of some sort.
