Working in the Houston Texas area, I see quite a few deer heads, horns and exotic animals. The hunters I've met have quite a passion for their trophies on the wall.
I've learned to incorporate then into their homes when decorating, especially for move-in decorating and they look fantastic.
When it comes to home staging, I've found that they can be used tastefully and subtly to enhance a room, more so with the horns vs. the entire head.
I don't want to sterilize a home when staging, but leave some personality in it while still making it neutral and appealing to potential home buyers.
Some nice examples below:
