Here is a picture I took a couple summers ago. The Wrigley Building is on the left, the Tribune Tower is on the right, and the middle one is the Hotel Intercontinental. The second flag down is that of the State of Illinois. The third is the flag of Chicago. The two blue lines represent the north and south branches of the Chicago River. The three white lines represent the north, west, and south sides (Sorry, no east, G). The four red stars stand for: Fort Dearbourn massacre of 1812, The Chicago Fire of 1871, the Columbian Exposition of 1893, and the Century of Progress exposition of 1933.
