In the picture, Thor rides in a horse drawn chariot, his hammer Mjollnir raised over his head and illuminated by lightning bolts.  Thor is blonde with a set of horns on his forehead.  He wears a red tunic with a golden sash.  Below and behind the chariot are half-naked humans and long-horned goats, which are battling with Thor.
