EPQ help- Stalin's cult of personality

I only do this at A Level but my first thought might be trying to look for some issues of Pravda, especially ones which feature things about the 5 year plans since they would heavily praise Stalin and I think should show the cult of personality. Another place to look could be letters or comments, one thing I saw in one of my textbooks was something called "marfa's letter" I think, and it's a woman in Magnitogorsk writing about why she thinks the targets of the 5 year plan isn't being met (she praises Stalin and blames the failure on others). Finally you might be able to use propaganda posters to show how Stalin was depicted. The SHP textbook does a nice progression of the Cult of Personality by showing how initially he was portrayed as quite modest, whereas by 1953 he was portrayed in god-like fashion. I don't currently have time to look for sources of the things I've mentioned, but I hope this helps.
