"Friday Foster" was based on a newspaper comic strip that debuted January 18, 1970 by writer Jim Lawrence and artist Jorje Longeron. It was the first mainstream comic strip with a black lead character. The movie gives a "thank you" credit to Chicago Tribune Syndication which licensed the comic strip to newspapers. Ironically, by the time the movie was released in 1975, the comic strip was no more, having ended the previous year.
