Ed,
Not sure where you are, but there is a lot of "tree art" on aspens here in Colorado, that was carved by Basque (and other nationalities) sheep herders that is unique and also tilting like "The Old Man". It really should be preserved if possible. It's called "defacing living trees" now, so most of lot is by Anonymous. A signed peice is rare. Take him home and preserve him, he is a true wood spirit!
