One more thought...
I love seeing how you display your trophies in Europe - very classy! In looking at those tusks - I can't help but wonder if - when the boar's tusks wear to the nerve within the tooth - if it wouldn't be very painful. Is there an age when they are more grumpy and tempermental? Because, if there's a nerve in those teeth (and why wouldn't there be?) it must be very very painful when they first expose it.
Anyways, random thoughts...great looking trophies!
