Murakami-Wolf-Swenson

Background
MWS was a joint venture between animators Jimmy Murakami, Fred Wolf, and Charles Swenson. It began as Murakami-Wolf Productions in the 1960s, and became known as Murakami-Wolf-Swenson in 1978. The company opened its Dublin office in 1989.

Logo (December 28, 1987-March 2, 1992)
Visuals: In a stylized font on a white-to-black gradient background, the capital letters M, W, and S (in a stylized font and red-white gradient going from the top to bottom of the letters) and the word "inc" (the same font, lowercase letters, and approximately 1/3 the size of the MWS) next to it. Underneath the logo, in smaller white letters, is "Murakami · Wolf · Swenson".

Variant: On Toxic Crusaders, the logo was seen between "A" and "PRODUCTION".

Technique: None.

Audio: In most cases, it's the last few seconds of the show's ending theme.

Audio Variant: Starting in 1991, a comical-mystery sounding synth tune is heard, produced using an E-mu Proteus 2 Orchestral synthesizer.

Availability:
 * It can be seen on every series they produced, beginning with the 1987 Teenage Mutant Ninja Turtles series as well as James Bond Jr. and Toxic Crusaders, respectively.
 * The standard logo does not show up on the 11 episodes of Alvin and the Chipmunks they produced; they instead end with the 1982 Ruby-Spears logo (since Ruby-Spears farmed out those 11 episodes to MWS.).
 * However, the logo proper can also be seen on the 1991 special Rocking With The Chipmunks, which appears on the 1992 Buena Vista Home Video release of said special.
 * This logo also appears on the 1987 Teenage Mutant Ninja Turtles series on the Official Teenage Mutant Ninja Turtles YouTube channel as well.
