The World War I Flying Ace by Charles Schulz

Schulz introduced Snoopy's most famous alter ego, the World War I flying ace in the mid 60s as a way of commenting on the Vietnam War. But at the very moment this anti-war momentum picks up, Charles Schulz kills this storyline. In 1968, Schulz added a new character, a black character, to the strip,. And I was really blown away to learn the backstory behind this introduction.
