Sib Tower 12 Productions

Background
Sib Tower 12 Productions (formerly "Sib Productions, Inc.") was an animation studio founded by Chuck Jones in 1962, after he was fired from the Warner Bros. cartoon department. In 1963, Sib Tower 12 received a contract from MGM to produce new shorts for Tom & Jerry cartoons (the previous shorts by Gene Deitch were proven bad). When the production founded acclaim, MGM purchased the studio in 1964 and renamed it to "MGM Animation/Visual Arts", which made many successful shorts and was closed in 1970 after Jones and his crew were fired. All ST12-library with the pre-1986 MGM library was purchased in 1986 by Ted Turner, which is now part of Turner Entertainment Co., now a subsidiary of Time Warner (Later WarnerMedia, then Warner Bros. Discovery).

Nickname: "The Arrows"

Logo: At the beginning of the cartoon after the cartoon title, we can see the logo "A SIB tower 12 inc PRODUCTION", all words in different styles. The "tower" is handwritten. The logo has two arrows, a filled one above, an empty below. It comes on a solid color background, but it was also spotted on cartoon action background.

FX/SFX: The logo fading-in and out.

Music/Sounds: The theme of a cartoon.

Availability: Rare.
