The Chicago Tribune: "Ramping up his campaign against the Art Institute of Chicago's pending 50-percent general admission increase, Ald. Ed Burke (14th) is trying to compel the museum to increase its free hours by enforcing an ordinance that is more than 100 years old. Burke said Monday that city lawyers believe the 1891 agreement between the Art Institute and Chicago remains valid .... The 1891 contract ... specified that the Art Institute would offer free admission on Wednesdays, Saturdays and a half-day on Sundays."
