From 1974 a Sinn Fein Manual of Publicity. It was an internal publication “..prepared solely for the information and guidance of Sinn Fein Members. It is not for public sale or distribution.”
It is fairly detailed and covers all areas of publicity from songs and poems, stickers, leaflets to cultivating contacts with the press and so on. An interesting read. I presume other parties produced such material also.
Many thanks to the sender.
Its fairly large so I have uploaded it in pdf. . Click on the link below or image below to launch.
