I must first apologise for the long hiatus, I was busy with other stuff including putting together a book which I shall plug ad nauseum at some point in the future.
This Christmas card-styled pamphlet fell out of a book in my dad's collection a few years ago. Alas, he had already flitted off to another realm so I didn't get a chance to ask him how he came about acquiring it. It is from 1971 and was published by People's Democracy as a protest against internment in Northern Ireland. Internment had been introduced as part of Operation Demetrius which saw 100s of mainly Catholic/Nationalist civilians arrested and detained without trial. This activity was legally justified by provisions of the Special Powers Act (NI) as described. Long Kesh is where the internees were imprisoned. The Nazi figure is Brian Faulkner, then Prime Minister of Northern Ireland. Faulkner was the last Prime Minister of Northern Ireland, serving from March 1971 until March 1972, and had presided over Operation Demetrius' implementation.
