The story comes from a Swedish poem about a space journey. Mankind has destroyed Earth and cannot live there anymore. They travel through space in a spaceship that broke down after start. They have no longer control over ship.
This drawing is about when dead people talk through stones about the horrible explosion that made Earth, ears and eyes broke down. They shout with Kassandra and the guide in the spaceship get the sad message through their jumbotron-like screen that his beloved is dead.
