INFO:
Recently, I acquired a lot of VHS Tapes from Japan. This episode of the 1973 Babel II series was on one of the tapes. This is the final episode of the series. I believe it was broadcasted sometime in the mid 1980s judging by the other tapes I purchased from this seller. The commercials from the original broadcast are intact, (Keep an eye out for the Sazae-san ad near the middle!!) and there's also text from a news bulletin that appears onscreen during the first few minutes. I don't think I have any other episodes from this series, but if I find any more, I will update this page accordingly.
