Sib Tower 12 Productions

Background
Sib Tower 12 Productions (formerly "Sib Productions, Inc.") was an animation studio founded in 1960 by producers Walter Bien and Les Goldman. Animator Chuck Jones would join the studio in 1962, after he was fired from the Warner Bros. cartoon department. The following year, Sib Tower 12 received a contract from MGM to produce new shorts for the Tom & Jerry series. The year after that, MGM purchased the studio, renaming it "MGM Animation/Visual Arts". In 1970, following the box-office failure of The Phantom Tollbooth, the studio was shuttered and Jones and his crew were laid off. Shortly after, Jones founded his own studio: Chuck Jones Film Productions. In 1986, the Sib Tower 12 cartoons (part of the pre-86 MGM library) were purchased by Ted Turner and are now owned by Turner Entertainment Co., currently a subsidiary of Warner Bros. Discovery.

Logo (July 27, 1963-January 27, 1965)
Visuals: At the beginning of the cartoon (after the title) is 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 one below. It comes on a solid color background, but it is sometimes superimposed on the opening scene.

Early Variant: On Rod Rocket, the logo is in-credit and it scrolls up with the other credits. Below it is the I.A.T.S.E logo and a copyright notice. "tower 12 inc" isn't shown on the logo.

Technique: A still printed cel, sometimes superimposed.

Audio: The opening theme of the cartoon.

Availability:
 * It was first seen on Rod Rocket, the first Filmation cartoon.
 * The later variant can be seen on the five of the earlier Tom & Jerry cartoons directed by Chuck Jones in 1963-1964 on Cartoon Network and Boomerang and it has also been preserved on DVD releases and HBO Max.
