World Map Feature Wall

I am currently re-doing my son's room who has just turned eleven. The colours which we have chosen are black and light blue with pops of bright red. I liked white with red and blue for a boy's room but then I think if it's black and blue he might be happier with it through to his teens. I would love to do a wall like this, any ideas where I can get such a huge map, is it a wallpaper?


The only thing I could find so far is this decal which won't look as good.
