CBS' Famous Classic Tales produced just 29 episodes over the course of 10 seasons (1970-80), the last of which rolled out in time for Thanksgiving of 1979.
Air Programs International produced the final episode, an adaptation of The Adventures of Sinbad.
As it turned out, Hanna-Barbera, through their newly acquired Australian studio, only made a handful of cartoons for the series.
No rating. Didn't see this the first time.
