Cause I really need some answers. First if you have seen this promo. http://www.i-mezzo.net/log/2004/07/06000015.html I can tell it's big by the pic but if you've seen it in person could you give me a rough estimate. Also what do you think it is made of? It look like paper behind plastic but I'm not sure. In any case I want it so If it comes up on Yahoo JP or if anyone has the balls to go running out of the station with it (not that I'm recommending that) PM me.
From the look of it from those pictures, its at least 5 feet high. Its probably made from heavy stock paper like all the other advertising posters. Only one problem with your plan, the frames are solid metal, locked and sealed to prevent people stealing them, and to protect them from the elements. That and its about 15 feet up... You would need to know someone who works for the company that changes the posters and/or be there at the right time when they change them, and be cheeky enough to ask for one.
LOL, I saw that on my first days in Tokyo, I even took a picture of it with my FF crazy friend in front of it, but its on his camera so I dont have it here. I think 5 feet high is a pretty good estimate. I didnt really bother looking what it was made of though... also, this is not the only FF advert in trains/stations, there were at least two others - a small FF:BC one and once for Advent Children, saw them on the Tokyo JR trains.
