“Explain your religion in one picture”

lol Trotsky as Judas

But where’s Rosa?

Found an image with higher resolution, but unfortunately not of the whole picture: https://lemmygrad.ml/pictrs/image/iCHSskBfnM.jpg

I recognize Che, Kim Il Sung, Castro, Ho Chi Minh (?), Mao, Engels (?), Marx, Lenin and Stalin. But who are the four on the left of the picture?
