This banner was ( may still be ) located inside garage portion of Tesla Motors Chicago store. I was asked if I wanted to sign it. At first I declined because I have a very lousy signature. But I was later talked into giving banner a bit of writing. If you look closely you can see a very sloppy signature with my name. Granted not my given name. The one most people know me by. Keep in mind I had camera in my left hand while writing with my right.
