Few buildings in Chicago are more iconic than the Chicago Theater.  It’s best known for its colorful sign, however, the interior is great as well.  The theater opened in 1921, so nothing but history here.  The theater does offer tours on days with no events.  This building (and sign) look different in every light.  Worth trying to capture morning, afternoon and as it’s lit up at night.
