I have a tie with Elly May Clampett and Lisa Douglas saying " This has been a Filmways Presentation "

From Wikipedia https://en.m.wikipedia.org/wiki/Filmways#:~:text=Green%20Acres%3A%20Lisa%20Douglas%20(Eva,a%20Filmways%20presentation%2C%20darling.%E2%80%9D

Most productions ended with the announcement, “This has been a Filmways presentation”. For some shows, the voice-over was made by a cast member:

Petticoat Junction: first, Billie Jo Bradley (Jeannine Riley) and later, Betty Jo Bradley (Linda Kaye Henning)
Green Acres: Lisa Douglas (Eva Gabor), who says, “This has been a Filmways presentation, darling.”[7]
The Beverly Hillbillies: Elly May Clampett (Donna Douglas). Following a few episodes, the voice of Jethro, Max Baer Jr., can be heard saying, "Aww, shuddup, Elly May", following her announcement. Seasons 1–3, however, feature Bill Baldwin, the announcer for the show's sponsors.
Mister Ed: Roger Addison (Larry Keating). Later seasons feature Mister Ed (Allan Lane) saying it after Keating's death in 1963.
The Addams Family: The logo was silent, but in some episodes the phrase was recited in a deep baritone voice by Ted Cassidy, although he did not use his usual “Lurch” voice. A few other times, Carolyn Jones recited the phrase and added "darling" at the end.
Ownership of film, television properties

Yeah, I'd call it a tie between later BH and GA.

I'd call the retention of these old logos a win, since many of them are scrapped in favor of the latest one.

I always found the "Green Acres" version with Eva Gabor saying "Daahling" quite amusing.

When Mister Ed was on Wednesday nights in 1965 I thought the voice sounded like someone talking through a speaker. It wasn't until years later I discovered that was Rocky Lane, the voice of Ed himself.
