In the upper left corner there are two short red stripes with blue text between them over the top of blue text that goes across the button on a white background, the button half of the button is blue with white text.
This button is from Richard M. Daley's 1989 election campaign to be mayor of Chicago. Daley, the son of previous Chicago Mayor Richard J. Daley, was up against Eugene Sawyer, who had been appointed to the position in 1987 after the previous mayor died halfway into his term as mayor. Daley won the 1989 election and went on to hold the position until 2011. Daley's tenure as mayor was characterized by increased benefits to LGBT workers, encouraged tourism, and instituted more eco-friendly measures around the city of Chicago. When Daley stepped down from the position in 2011, he had served as Mayor of Chicago for 22 years, making him the longest-serving mayor in Chicago's history.
