Warner Bros. Classic Animation

1930-1931
Warner Bros. started making classic cartoons in 1930 but did not use a logo until the following year; instead, an in-credit notice that says "WARNER BROS. PICTURES & THE VITAPHONE CORPORATION PRESENT" is used for the animation studio's 1930 cartoons.

1931-1933
Starting in 1931, the Warner Bros.' animation studio introduced its first logo, which would be used on Looney Tunes cartoons until January 1936 even though Merrie Melodies cartoons continued to use it until the following month.

1933-1934
In 1933, the logo itself remained the same but the WB shield was modified and given a different design.

1934-February 1936
In 1934, the banner is now in two rows and has been modified to say "Warner Bros. Productions Corportation". This is the last version of the logo. The last cartoon to use this logo was The Cat Came Back.

April 1939-June 1940
In April 1939, "Vitaphone" was changed to feature "Warner Bros." (which is in a serif font) and "presents" was replaced by "present" after "Vitaphone" and "presents" has retired. The first cartoon to use the Warner Bros. moniker was Porky and Teabiscuit. Also, from Porky and Teabiscuit to Hare-um Scare-um, a yellow banner was used while the normal version without the yellow banner debuted on Detouring America. There is also a variant in Believe It Or Else where "Warner Bros." appears in a sans-serif font from the Looney Tunes openings in 1939 and the WB Shield is large like in the "Vitaphone" "presents" cartoons from 1936 to 1939. The green-yellow rings from the previous logo was used in April 1939 and its was retired in September 1939. The last cartoon to use the green-yellow rings was Souix Me. The normal version with the red white and blue rings debuted on Land of the Midnight Fun.

On cartoons in 1940, the copyright's year says MCMXXXX instead of MCMXL for some reason.

November 1944–1948


In 1944, the words "Pictures" and "Inc." were added to the "Warner Bros." moniker and the shield was updated again.

1947–1954


In 1947, the shield was updated yet again.
