Anyone know if Hanna-Barbera produced this particular series of Kool-Aid commercials? I know Tex Avery worked on some other Kool-Aid commercials from the same era but I don't think the ads with the Kool-Aid twins touring the world are from him, these ones look much more like early Flintstones.

Bugs Bunny appeared in the final (?) ad in this series, the one the Winter Carnival, but that was right at the end of that commercial, I don't think Warner Bros. made the rest of the commercial, though Warner did make some other Kool-Aid commercials featuring Bugs Bunny.
