Gotta love this WPA-style mural, which humbly reminds union members that “The plumber protects the health of the nation.” The White Castle-like building on the right is the old Water Tower — one of the few buildings to survive the Great Chicago Fire of 1871. In front of the plumber is Buckingham Fountain, known to Europeans as “Bundy Fountain” from the popular T.V. show “Married with Children.” The show still airs daily in Norway.
