Question: How do wrapped advertisements work? Ones where they wrap an advertisement around a subway train, for example? I've seen it on buildings also. How do they make sure the picture is evenly applied when the surfaces are so uneven?

Answer: If there are uneven places, they would need to be behind background areas that would not be noticeable, unless there is a high-tech adjustment on the printing end that I kind of doubt (cost-prohibitive). Otherwise, I suppose it would stick on like any billboard, using smaller connecting sheets.
