Edith Tudor Hart was in South Wales in the 1930s following her husband's appointment as a GP there. As communists they would have sympathised with the economic hardship of the miners in the Rhondda valley. During the industrial depression following the First World War, unemployment figures in the area soared. With the help of other unions, the National Unemployed Workers' Movement (NUWM) organised Hunger Marches, which demanded more fair unemployment legislation. This photograph was taken during one such demonstration, with the photographer perched on a post opposite the crowd of men.
