Unlike changing the wallpaper on your computer, changing the wallpaper in your house can be an expensive affair. At $23,700 per sq meter, it definitely is, but not for a Russian billionaire who has asked the well known Artist Mark Evans to create what will be the world’s most expensive wallpaper. The total project is estimated to cost around $2.84 million to wallpaper two rooms in the billionaire’s house in Moscow. While the impulse to bring something of this sort into the home is not new, you’ve got to be an avid art lover to etch such a timeless wallpaper in your décor. Via: Faded Tribune
