An illustration of the Chicago Picasso sculpture on a yellow background with curved red text on the right and left side of the illustration . 

The picture on this button is that of an untitled Picasso piece that is located in Chicago. Picasso’s designs for the eventual structure were not original, but instead he modified designs he’d made in the early 1960s.  A local architect, William E. Hartman, then turned the design, with the help of the United States Steel Corporation, into the actual statue. The mayor at the time, Richard J Daley, unveiled the statue to the citizens of Chicago. The piece has the honor of being the first monumental outdoor Picasso in North America. It was dedicated on August 15, 1967.

Peter Fox Sons Co. was a Chicago-based year round turkey company. The company was created in 1897 and was run by nine Fox brothers when their "DeLuxe" turkeys went on sale. They were the first company to teach turkey-growers how to "dress" their own birds, saving the company time and benefiting the growers with more money. They were also the first company to pack and sell turkeys under a private brand "DeLuxe".

In 1902, janitors, elevator operators, and window washers in apartment buildings organized the Chicago Flat Janitor's Union, the nation's first union of building employees and the forerunner of the Service Employees International Union (SEIU). Most members were immigrants, and the union's leadership and membership crossed racial and gender lines from its inception. Goals included higher wages and better working conditions and, because janitors often lived in dank basement apartments in buildings where they worked, better living conditions. In 1921, the Chicago Flat Janitor's Union became Local 1 of the new Building Service Employees' International Union, later the SEIU, an AFL union headquartered in Chicago until 1990.

This button commemorates the 150th "birthday" of Chicago, Illinois. Chicago was incorporated in 1837 and was a transportation hub. It was the site of the Chicago Portage and received its first railroad line in 1848, which helped link the western and eastern United States. By the 1850s, the geographic location and importance to shipping had enabled Chicago to become a political center, too. I was the home of Stephen Douglas and the location where Abraham Lincoln was nominated by the Republican Party. In 1871, a fire destroyed large section of downtown Chicago. The fire excluded its railroad and stockyards, so the raw material of its economy remained intact. Chicagoans rebuilt a modern city made of steel and in 1885 it became home to the nation's first skyscraper.

In 1893, Chicago hosted the World's Columbian Exposition, which celebrated the city, the nation, and the triumph of Western Civilization. By end of the century, Chicago had also become a city of immigrants; one in three were foreign-born. In the early 1900s, Chicago became a industrial city as well. The industrial jobs brought African-Americans from the South to Chicago. The newcomers brought with them a culture that flourished, contributing the the Black Renaissance and the New Negro Movement. It also brought race riots when in 1919 the white and black Chicagoans violently attacked each other over housing and job market concerns. 1919 was also the first year of Prohibition, which helped introduce Chicagoans and the nation to many popular gangsters, such as Al Capone and Bugs Moran, which culminated with the St. Valentine's Day Massacre in 1929.   

In celebration of the city's one hundredth birthday, it, again, hosted a World's Fair in 1933 and 1934. Its theme was the technological progress, and there were few cities better suited to host it. By the 1940s, Chicago became the home of the world's first nuclear reaction as part of the Manhattan Project. After WWII, Chicago, like many major US cities, saw an out flux of whites to the suburbs. The demographic shift changed the city's make-up and changes in Chicago's industry led to job shortages in the early 1960s. By then of the decade, Rev. Dr. Martin Luther King, Jr. and the Civil Rights Movements had begun working with the city's political machine to improved the situation. The agreements did not apply to more radical groups involved with the 1968 protest of the Democratic National Convention, which ended in a city riot. It was business as usual by the 1970s and major construction projects erected the Willis (Sears) Tower, the University of Illinois at Chicago, and the O'Hare International Airport. In 1983, Chicago elected its first African-American mayor who was reelected in 1987 and later died.

A portrait photograph of Cardinal George Mundelein. 

George William Mundelein (July 2, 1872 - October 2, 1939) was the archbishop (1915-1939) and cardinal (1924-1939) of Chicago.

He strove to unify the ethnic Catholic groups such as the Poles and Italians into one parish, the effort was somewhat successful. As a moral leader, Cardinal Mundelein condemned Adolph Hitler and wished to establish a higher learning facility for Catholics in Chicago. He founded St. Mary of the Lake Seminary in Area, Illinois, a town northwest of Chicago. Area later changed their name to Mundelein in his honor.

The Anti-Litter club was formed by the Chicago Park District. This club is mentioned in a 1934 newspaper article that explains that the club was used to educate citizens of the effects of litter. In 1934, 12,000 waste baskets were put in Chicago parks to help promote clean parks and no littering.
