Warner Bros. Family Entertainment (1993)/Warner Bros. Cartoons (1958)
Well here's a logo combo that is completely unexpected to be found on TV broadcasts of classic Looney Tunes shorts, especially on the Turner networks; in this more recent Boomerang USA airing of the Sylvester and Tweety cartoon "A Pizza Tweety Pie" (1958), the 1993 Warner Bros. Family Entertainment logo (albeit with the theme music muffled on the mono track, and different sfx used for Bugs Bunny's carrot chomping) is seen before the cartoon, something which is never found on previous airings of this cartoon on CN/Boomerang USA, let alone other TV airings of this cartoon in other countries, including Tooncast in Latin America, Mediaset Italia 1 in Italy, RSI LA 1 in Switzerland and various international CN/Boomerang feeds.
Recorded from a recent airing from Boomerang USA on 20th September 2020 (Credit goes to Cool_Cat from Toonzone/Anime Superhero for sharing with me this Boomerang USA TVrip of "A Pizza Tweety Pie" in HQ).
