English Russia has a gallery of unsettling psychiatric hospital posters from Soviet Russia.
Sadly, my Russian is not quite as good as it should be but they seem to be a mix of flowchart style information telling staff how to deal with clinical situations and information about different sorts of disorders.
Needless to say, the bleak photos and unsettling graphics don’t make for the cheeriest combination but they are certainly an interesting insight into a small part of psychiatry from an earlier Russia.

My Russian is alive and well if a bit rusty, so if you’re interested in a particular poster I can help. The illustration above shows symptoms of thyrotoxic crysis.
