On July 31, 1968, Peanuts creator Charles M. Schulz broke down barriers by introducing the strip’s first African American character, Franklin. Now, 47 years later, The Peanuts Movie is celebrating his first appearance with a social media campaign illustrating the character’s background.

Following the death of Dr. Martin Luther King, Jr., a teacher by the name of Harriet Glickman wrote a letter to Schulz expressing the importance of adding an African American character to Peanuts, the country’s most popular comic strip at the time. As stated earlier, Franklin Armstrong made his debut on July 31st, 1968, and represented the importance of desegregation and equality.

Nearly 50 years later, America still struggles with racism and racial inequality, especially in light of the rampant reports of police brutality and hate crimes recently, something fun like #FranklinDay is a way to celebrate and promote something positive. And hey, it works as a very smart and creative marketing tool for The Peanuts Movie.

Re-live Franklin’s first appearance in Peanuts below, and Happy #FranklinDay!
