This is a really nice wallpaper that BlackBearBlanc uploaded to his dropbox. BlackBearBlanc is well known over at the XDA forums for his minimal android setups and fantastic wallpapers. To download, check out the source. I highly recommend checking out his tumblr page, his XDA profile page, his dropbox, and his home screen setup with the book wallpaper for inspiration. Note: It will work as a desktop wallpaper too.
