My friend Richard Grayson posted interesting side-by-side photos on his Facebook page, which are shown above. Both photos are of 311 Washington Avenue - the first in Brooklyn, the second in Miami Beach. I thought I'd do likewise for Chicago and Joliet. Here is 311 W. Washington Street in Chicago:
This building is half a block from my office, and primarily houses an AT&T switching station. (Interesting how those utilitarian AT&T buildings were designed so ornately back in the old days.) And here is 311 E. Washington Street in Joliet:
Not much to see here, other than the Rock Island railroad embankment and a sliver of the roofline of Joliet Central High School. But this address is somewhat historically significant, as the opposite side of the street is the former site of the Gerlach-Barklow Company, which was once one of the biggest manufacturers of art calendars in the United States.
(Note: There is no 311 E. Washington address in Chicago; that number would be located somewhere in the middle of Grant Park. And 311 W. Washington in Joliet would be in the middle of an intersection, so thus the street address doesn't technically exist either. So, the Chicago and Joliet addresses I used above were the closest matches to Richard's addresses.)
