Pig at Trough Folk Art Ashtray

Such a fun thing, which if not to be used as an ashtray, might make a memorable business card holder, or could serve sink-side for stashing rings. It's heavy, and definitely more or less industructible, with a great patina to the metal (which I believe is brass but I guess could possibly be steel given a brass-like finish), and which is screwed to the thick wooden base. Found in Massachusetts but I have no idea of its origins.  7 1/2" long x 5" wide x 3 5/8" tall and in perfectly aged condition.
