Back features Sergey Yesenin's "Hear Sled Race" poem (I couldn't find a good translation, not sure how accurate this is...)
The front design is an edit of Vasily Perov's "Seeing the Dead Man" which was also used for the original art of Drudkh's Blood In Our Wells
I have no idea of what this design means, I'm guessing it may tie into Carju Niebiesnyj or Raskol's lyrics, but I don't speak Russian/Polish/Old Slavonic to know what the lyrics are
