As is the custom today, people at the time of Haymarket wore small pins or related items on their lapels or other parts of their clothing to signify their membership in a certain organization or support of a particular cause. Even though the Knights of Labor head Terence Powderly denounced the violence at Haymarket and opposed clemency, Albert Parsons, who was a member of the organization, went to the gallows in a vest bearing a button with the Knights of Labor seal.

At the unveiling of the monument at Waldheim in 1893, Lucy Parsons was described as dressed in deep black and wearing at her throat "a small golden gallows which is in many parts of the land affected as a badge of Anarchy." But pins like the one on view here (almost one inch high) were also worn by those of varying political beliefs who felt the defendants were unjustly convicted or who had advocated clemency. This wonderful artifact, which captures both the elevation of feeling behind the clemency movement and the brutality of the punishment inflicted, is inscribed "Nov. 11 1887," the date of the executions.
