Looking back at old photos of any city is pretty cool. Chicago is no exception. Thanks to our friends at Calumet412, a fantastic Chicago photo history blog, we get to remember what the city looked like at various points throughout time. We asked Calumet412 for some great images of life in Chicago in 1893, the year the CAA first opened. Take a scroll through the slideshow. Want to see more? Pop by Calumet412 and be prepared to waste a lot of time in the best way.
