The badge/pin was designed for a member or the Mohawk Valley chapter of the Renegade Pigs Motorcycle Club.
The original design had a boar head on an iron cross with a slot or loop to hold wrist bands or sunglasses with the loop versions.
This is only the boar head. These badges do not come with a backing, your local jewelry repair shop can attach one. I had locking pin clutch backs attached for $12.00 each.
