The Voice of Labor. Vol. 11 No. 610. July 21, 1923.
The Voice of Labor was a regional paper published in Chicago by the Workers (Communist) Party as the “The American Labor Educational Society” (with false printing and volume information to get around censorship laws of the time) and was focused on building the nascent Farmer-Labor Party while fighting for leadership with the Chicago Federation of Labor. It was produced mostly as a weekly in 1923-1924 and contains enormous detail on the activity of the Party in the city of those years.
