“We’d like to thank you all for flying with us today and the next time you decide to go hurtling though the air in a large aluminum tube we hope you choose United Airlines.”

This is Dialogo by Italian artist Virginio Ferrari. He was born in Italy and lived in Chicago. The sculpture is located on the University of Chicago’s campus and every year on May Day it casts a shadow that resembles the hammer and sickle on the U.S.S.R’s flag. The artist claims that this was totally unintentional but rumors persist that say he was a communist sympathizer.
