Afraid I don't have any posters, but I was looking through the Tumblr that's been set up and this one's been mis-tagged as being Warhammer. Easy mistake to make, but that Warmachine and Hordes - guys in the trench are from Warmachine, the thing above them is from Hordes.

Just thought I'd mention it in-case anyone was trying to find Warmachine/Hordes posters and that didn't come up.
