Stalin mugshot; ca. 1911-Tsarist Russia

Say what you will about the man; he had a hell of a mustache.

You can see his gimped left arm in that photo:

“As a child, Ioseb was plagued with numerous health issues. He was born with two adjoined toes on his left foot. His face was permanently scarred by smallpox at the age of 7. At age 12, he injured his left arm in an accident involving a horse-drawn carriage, rendering it shorter and stiffer than its counterpart.”
