I think we’re talking about people in this country right now in 2016 and what marks them out as Tories. Actually find @pervo’s comments interesting because they aren’t what I would classically mark out as Tory things but then my view is set in the 1980s.
(I am presuming you are talking about posters in countries like Cuba, USSR, China, North Korea etc. not Communist Party of Great Britain, etc.? And there’s obviously something to be said about how many of those regimes really represent socialist/communist ideals in anything more than name.)
