Simply someone there has one of these $350,000 superwide billboard inkjet printers.
Maybe, but we are looking at a four hour time frame from bombing to poster display. Even with the top end machine, which we do not know they had, it is still a stretch.
Are those pictures all one-piece, and locally printed?
It's hard to tell with the Coke ad whether it's one piece or not (and that's also the type of thing that gets shipped)...but aside from that one, the only one with an object that suggests scale shows one that is probably only 8' tall.
