Langston Hughes sign at May Day Parade, New York City, May, 1933.

During the 1930s, John Albok took thousands of pictures of May Day parades. This one shows an interracial group of marchers carrying signs about racial equality. One sign shows a portrait of the "Famous Negro Poet" Langston Hughes, and quotes these lines from his poem, "A New Song": I speak in the name of black millions awakening to action. The Black and White World shall be one: The Workers' World."

Another sign reads in part: "14th Amendment to the Constitution, Section 1: No states shall make or enforce any law to abridge the rights of citizens of the United States nor deprive any person of life, liberty or property without due process of law."
