On 13 August 1961, the German Democratic Republic (East Germany) started building what became known as the Berlin Wall. This sudden development in the Soviet bloc caused Communist Parties around the world to come up with arguments to support this move by the GDR. Here is a pamphlet (probably) distributed by the Communist Party of Great Britain in the early 1960s to defend the Wall.
There is no authorship attributed on the pamphlet. If anyone knows anything more about this pamphlet, please let me know.

Oh wow, thanks for sharing! I am writing on a larger book on the social history of German migration, 1961-1989 and have a copy of the German original. It was distributed to Western visitors to Eastern Berlin and most likely published 1964. One difference I instantly realized is that under point 6 the German version also mentions the border cinemas among the centers of evil in Western Berlin. It also had an even more rude and aggressive predecessor “Why the wall and how long?” most likely published in 1963. Again, thanks for sharing and I would be more than interested in learning more about the distribution of this (of similar) pamphlets in Britain!
