Summary of the returns received by the South Wales Miners' Federation regarding the number of colliery workmen unemployed in the South Wales and Monmouthshire coalfields for the week ending 10 September 1921
In 1976, the National Union of Mineworkers (South Wales Area) deposited Andrew Turner's dramatic portrayal of the 1921 lockout with the South Wales Miners' Library. The three panels depict solidarity, betrayal and defeat.
