I don't know what the exact difference is between 'outdoor art' and 'poster', but this outdoor art for 3:10 to Yuma definitely looks like a cool new poster.
Movie Poster, I Mean Outdoor Art for 3:10 to Yuma
In Arizona in the late 1800's, infamous outlaw Ben Wade (Crowe) and his vicious gang of thieves and murderers have plagued the Southern Railroad. When Wade is captured, Civil War veteran Dan Evans (Christian Bale), struggling to survive on his drought-plagued ranch, volunteers to deliver him alive to the "3:10 to Yuma", a train that will take the killer to trial. On the trail, Evans and Wade, each from very different worlds, begin to earn each other’s respect. But with Wade’s outfit on their trail – and dangers at every turn – the mission soon becomes a violent, impossible journey toward each man's destiny.
Though I still like the first poster better, I like that the new version is at least unique.
