Welcome to Chicago

Is this a recent development? If so, this would explain why everyone's driving seems to have gone to shit in the last few years.

I used to travel quite a bit for work and I would collect state themed magnets for my kids each time I visited a new state. Most airports have magnets for sale in the gift shops that are shaped like the state with some various references to the state. I visited Chicago multiple times, but I could never get an Illinois magnet because apparently Chicago overrides any acknowledgement that it is part of a larger entity...there is only Chicago.
