An episode of "The Buster Keaton Show", and three episodes of "Life with Buster Keaton" can be viewed on the Internet Archive. The former is a kinescope of a live telecast, and includes the original commercials for Studebaker cars. (This was an era where television shows typically had a single sponsor, with "The Buster Keaton Show" having three commercial breaks, each for Studebaker.)
