Wallpaper for a boys room with map of the world motif?

[pinkhousesarebest]

I am redecorating my d.ss room, and remember seeing lovely world map wallpaper in a magazine.Needless to say I can no longer find the mag. Anyone any ideas?

IKEA did them last week - poster the size of a wall. But seemed v popular and half the shop had one in their trolley!
