I vaguely remember there was a business, whose work was mainly pictures that wenton the outside of garage doors. They had one which was a fighter jet facing outwards, another was a tank.
If they can do it on outside, they can go on inside too? Probably correct about not being in one piece, but I gather it would go on in same manner as wallpaper. One piece at a time (to steal a line from a Johhny Cash song, same title!).
I'll try to find that business name. Worth a look at their artwork, if nothing else.
