That is one of Joe's earlier pieces and would have been made when he was in Alamo Texas, I'd guess early 1980s. I have some of Joe's catalogs from this time, but haven't looked at them in a while. I'd guess he sold that knife for $75 to $100.
Joe was killed in December of 2014.
Here he is in November of 2014
Here is Joe and Warren Osborne with a "deer tree" I miss both of those guys more than a lot.
