Shown here is a bison horn that I was provided by a client for engraving.  I was asked to do something primitive, along the lines of cave or rock paintings.   I really wanted to do something a little more sophisticated than that. What I suggested was some designs inspired by Micmac powder horn engravings.   The client agreed and that was what I endeavored to do.  He and you will have to be the judge of how well I did.
