Solidarity Day was a national labor march that took place at the Lincoln Memorial in Washington, D.C. on September 19, 1981. The march, attended by over 260,000 people, was organized in solidarity with members of the Professional Air Traffic Controllers Organization (PATCO), in response to a strike of over 12,000 members that began on August 3, 1981 against high stress working conditions that were put both members' health and the airline safety at risk. After only two days of the strike, then-president Ronald Reagan fired the air controllers and brought in military personnel as strikebreakers. The march was supported by the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) and participants came from a variety of organizations, unions, and civil rights groups to protest in favor of labor rights.

While Earth Day celebrations have taken place across the United States since 1970, this button commemorates the 1980 Earth Day festivities held in New York City. The event was held from 11:30 am - 2:30 pm, from 42nd to 52nd Streets, and included food and drink, live entertainment, exhibits and other setups on environmental themes, and more. The green heart design seen here was created by graphic designer Lancer Wyman specifically for this event. 

Around the rim are two brown lines with black text and five small, brown illustrations of people between the lines; in the center is large, stylized text with illustrations of a wide variety of human feet emerging from the bottom of the word "PEOPLES" and small text inside the letter "O" of the large text; all on an off-white background.

The Rolling Stones are a British rock band that began performing in 1962. They are estimated to have sold over 250 million records over the years. The band was inducted into both the Rock and Roll Hall of Fame and the UK Music Hall of Fame; and has been ranked number four and number ten of artists worldwide by Rolling Stone magazine and Billboard magazine, respectively.

Released on June 9, 1978, Some Girls is the 14th studio album by the Rolling Stones and is the single best-selling Rolling Stones record. The original album art featured a parody of a vintage wig advertisement, depicting the band members in drag as well as many iconic celebrities such as Farrah Fawcett and Lucille Ball. The band, however, did not obtain permission from the women and/or their estates and thus the original album pressings became collectors’ items as the band was legally prevented from printing more albums with the original art.

The NAACP, or National Association for the Advancement of Colored People, is the oldest and largest civil rights organization in the United States. Founded in 1909, the NAACP advocated for the rights and wellbeing of Black Americans with regards to legal protections, health, and economic opportunities. Buttons such as these were meant to be worn by NAACP members.  

The overall design has a three-dimensional round effect, with an illustration of a globe black text on top. The "O" and "K" in the word "McCormick" are red for emphasis. 

Cyrus McCormick (1809-1884) was a manufacturing visionary. McCormick utilized the financial means of then-mayor of Chicago William Ogden to set up a small manufacturing factory in 1848. During this time, an important canal opened—the Illinois & Michigan Canal—which linked Lake Michigan with the Illinois and Mississippi Rivers. In essence, McCormick saw then-small Chicago (population ~20,000) transform into a city rich with infrastructure and trade. Over the next few years, McCormick expanded the McCormick Reaper Works into “the world’s largest farm machine factory” (ASSEMBLY). By 1850, the factory had 200 employees working 100,000 square feet of factory space. 

By the late 1800s, the company had sent out farming equipment “all over the world” via its McCormick Shipping Line. Much of the company's advertising reads: "The OK Line, the McCormick Line, OK All Over the World and an All 'Round Success."
