CHICAGO (WLS) -- The city removed the lion statues from the Michigan Avenue entrance of the Art Institute of Chicago Tuesday morning for regular cleaning and maintenance.
A crane loaded the bronze statues onto a flatbed truck, en route to the city's conservation partner, where they will receive a steam cleaning and a protective wax coating.
