I know that this is an older post but I thought that I would put in my two cents.
I actually came up with an idea a while back and started a small business around it.
I provide, what we call, "WildlifeTags" for a mounted deer or other wild game. A WildlifeTag is a piece of leather that has been engraved to your specifications with the game info. We then attach a cord to the tag and hang it from the antlers. It has a very rustic look to it and many people do like it a lot.
It's a rather new concept and I would love any feedback on it.
