THE DARK KNIGHT Poster Rolled - "Coming Soon"

Further to a number of questions about this poster (and another Dark Knight poster we have listed for sale) we would like to clarify/confirm the following for this poster: 

It is single sided and measures 27”x39” (which is a very odd side for UK Cinemas). 

This poster and the other DK poster came as a pair to me from a guy in Denmark as a swap (for Kill Bill). 

I have worked in the film business for 25 years and have been collecting posters for over 40years - but this one (and the other it came with) have me perplexed. 

I can’t honestly say with 100% certainty that they are exhibitors posters but it is possible they were head office/agency prints. But I cannot say for certain. 

Any questions please do feel free to ask.
