This tree has many, many faces carved in it. Technically, this tree was defaced. (pun)
But, since it was done by a mad artist, I'll have to let it slide. In fact, you'd have a hard time even finding this tree, that's how minor the carving truly was. And the faces were extremely well done.
For a video slide show of all the faces, see this page: www.flickr.com/photos/_jfr_/5778173760/in/set-72157626719...
