Who cleans it Occasionally the artist him/herself, but frequently the city hires outside conservation contractors to get the job done.
Public art cleaning and repair tab for 2007 $73,480
Hardest piece to clean, according to the Chicago Department of Cultural Affairs Rara Avis, a 35-foot-tall sculpture of a cardinal, the Illinois state bird, comprised of more than 2,500 cast-metal airplanes suspended from steel cables. Hanging above the ticketing hall of Midway Airport, the piece is a dust magnet and requires maintenance crews to put in six to eight overnight-cleaning shifts per year to keep it clean.
Art maintenance budget for 2008 More than $100,000
