On the left it says something like "Soviet authority will only last two weeks!" and then on the right it says "15 YEARS - the USSR is finally established on the path to socialism"
It isn't really cursive Cyrillic so much as just italic Cyrillic. I struggled with reading italics for a good while too, but eventually you get the hang of it.
Edit: Oh and the heads on the left are labeled "monarchist", "cadet", "eser", and "menshevik".
