From 1979 an Anti Nuclear leaflet from The Irish Sovereignty Movement. According to wikipedia
The Irish Sovereignty Movement was a political lobby group in the 1970s and 1980s fronted by Anthony Coughlan who was its chairman. It held meetings and produced publications campaigning on various political issues mainly to do with Irish Independence and its relationship with the Common Market, EEC and European Community, Irish neutrality, as well as Northern Ireland.
