It's a diagram of how males of different races in the Soviet Union supposedly look, used by Soviet police to identify nationalities.
It's funny how the 'Tatar' looks just like Lenin, though Tatars weren't such a prominent part of his very mixed ancestry ("Russian, Kalmyk, Jewish, German and Swedish, and possibly others", according to biographer Dmitry Volkogonov.) It's strange that the 'Georgian' doesn't look exactly like Stalin (probably because this was post-thaw, when the Soviet regime had distanced itself from Stalin). I wonder if it's a pure coincidence that the 'Tatar', the 'Jew' and the 'Gypsy' are next to each other. And we suspect that when the artist got to the 'Tajik' and the 'Turkmen', it was already close to deadline or the end of his workday, so he just drew something random - that's why they look a bit more imaginative than the others.
Ainur can't get over how cute the 'Jew' is.
