What did Joseph Stalin look like?

According to a physical description the police circulated when he was a known revolutionary troublemaker, Joseph Stalin was only five feet, four inches tall.

The notice goes on, painting a less-than attractive picture:

Soft voice
Birthmark on left ear
Sunken, hazel eyes
Pockmarked face
Withered left arm
Second and third toes on left foot grown together
Thick, black hair and mustache (but no beard)
