Drivers heading west on Congress Parkway out of the city have been bid adieu since 2010 by a large Chicago Blackhawks mural located on the sixth floor of Chicago’s Old Main Post Office. See the wood propped up in the window on the left side of this photo? That’s the Blackhawks mural. I took this photo in February 2017, after the Old Post Office had sat vancant for 20 years. During that time, leaks in the roof caused the wood floors to buckle and expand, as seen here.
