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