I hope it is in good shape, if so you can clean it up and varnish it.
I have a picture of a Javelina shot by one of my ex-wife's ex-husbands...I'll have to see if I can find it.
I once found a cat carcass up in the woods that had died sometime before hand.
It's skull had been picked clean by elements and ants, etc so I took it home and cleaned it up and coated it with varnish. The lower jaw fits nicely into the top half and is quite a conversation piece.
As is my rabbit's foot that fell behind a shelf at the World Famous Treehouse gift shop where I worked years ago. It is just bones, looks like a little hand...it is funny to ask someone if they would like to see my rabbit's foot and I put it in their hand. It has been dropped many times...LOL
