This is another one that I designed out of boredom. It was late, the kids and wife were asleep, so I started messing around. I grabbed a pic of a motorcycle online. Cut the background out, ran some filters in Photoshop. I used a dingbat of a tattoo design - which is in the background and just manipulated it until I was happy with the look.
All of this is made up - there is no South Side Choppers.
