The Chicago Flag. I had no idea what it was when I moved here a few years ago, but now it is big part of our life. We have it on shirts, hats, coats, its in our house, it flies everywhere around the city, we see it everywhere. The burger place we walked to tonight (DMK Burger Bar) uses a modified version of it on their t-shirts. I saw a version of it with with lions in place of the stars on the way to dinner advertising some place called 3 Lyons. Some taxi’s have the modified look on their cars. Its everywhere. Really. The civic pride shown with this flag is amazing.
There is a great Ted Talk I found recently about the design of city flags in general and the Chicago City flag is one of the featured flags. If you like design or flags at all (or even if you don’t) take a few minutes to watch. Very fun.
