Red November, Black November is a study of the culture of the I. W. W. movement at the turn of the twentieth century. It analyzes the Wobblies' use of cultural expressions such as songs, poems, and cartoons as a means of educating and unifying workers, and as weapons in the struggle against the repressive social conditions of industrial development. The book emphasizes the important role played by immigrant activists, Wobbly artists, and intellectuals, offering a fascinating portrait of the complexity of pre-World War I labor radicalism.
