The union label originated in 1869 when the Carpenter’s Eight-Hour League in San Francisco used a stamp to identify products from mills employing men on the eight-hour day. Other, non-unionized mills, operated with a 10-hour workday.
The individual union labels below, are from The New York State Archives, and from the Labor Archives and Research Center of San Francisco State University. For more about the history of union labels, and the “hand-in-hand” symbol of the AFL-CIO, check out the site of art historian, Kim Munson.
