It could also be an old promotional poster for "Lo'Gosh", or a recently new reminder of "This is the enemy", a propaganda poster. It IS A Horde poster after all.
There has been an undeclared war, a "cold war" if you will, going on since Vanilla. Of course Garrosh would like to see Varian pushing up peacebloom just as the reverse is true. It was pretty much Thrall and Jaina that kept it from going all-out. Now that Thrall is out of the political picture, and Jaina will shortly have her opinions about the Horde changed for her by Garrosh, the pretense of non-aggression is all but eroded away.
