The badger is the mascot of my university, Brock. A badger is sometimes referred to as a "brock". It is prominant in the Brock family's coat of arms. The formal sporran seen in my avitar is of badger fur with brass.

"The badger is an animal noted for his fierceness and courage in fighting to defend his home. The symbol of the badger represents bravery, perseverance and protection. It is more typically found in the armor of England than that of other nations. " http://www.familynamesonline.com/charges2.html

My two oldest "chosen" children are Native American, so I can appreciate the lovely artwork. Well done!
