Thanks for the info, Aaron. The "Rainbow H-B" was first used from 1974 until 1979 where it was later replaced by a famous "Swirling Star" logo. That logo used from 1979 until 1986 where it was replaced by a CGI version from 1987 until 1990.

Thanks for posting you brought back so many memories. I remember watching these cartoons. I also liked seeing the previews on Friday night.
