Oxford's loss, Chicago's gain

My friend Dan Sinker launched a mini-twitter campaign yesterday to have the now-defunct "Oxford Comma" cross the pond and land in the city of big shoulders to become the "Chicago Comma". Because all great efforts need an icon, I decided to spend a few minutes making one for him. The icon is a modified version of a Gotham bold comma.

I know they're planning on using this, so I'll likely have to go back in and update the skyline so it translates to a small icon, but thought I'd share :)
