Emanuel also used the occasion to launch "the 50 for 50 campaign," in which he said the city will seek to install a new piece of public art in all 50 wards. "In every part of the places throughout the city where we're building either a new train station, rehabbing or rebuilding a park, we're going to add art pieces so those public spaces are reclaimed by the public and then enriched in experience of the art," he said.
