This is not the worst of the graffiti. The gray paint is the work of a censor. A man with a glass and a man with a cross appear to be in a cemetery. The man with the glass has a fleshless arm and leg so he could be a walking dead figure. The man with the cross seems to be coming out of the ground, has dark eye sockets and some sort of cloth on his head, he may also be a ghoul. It is hard to tell what the flying figure is.
