Time Traveller Spotted in Chicago

I was out recently and ran into proof positive of time travelers in ChicagoLand. I was immediately on guard.  After all, the only good time traveler is one who will give me the keys to his Type 40.

Clearly, the chameleon circuit in this one is busted, but luckily I can do repairs.  WIth time travel in my hands, you are all doomed.  Mwahahahahahaha!
