Look Back on Academy Award nominated/winning cartoons
(traditional theatrical shorts from 1930's to the 1960's)The 1930's"
Flowers & Trees", first full technicolor cartoon, won the first Oscar for animated short subject in
1932.

While it's innovative, I find the cartoon average. While I'm not exactly into cartoons from the early 1930's, I'm surprised no Betty Boop cartoons were nominated.
Disney pretty much dominated the "Best Animated Short Film" category until 1940 when MGM "The Milky Way" won.
"It's Got Me Again!", first Warner Bros. cartoon to be nominated for an Oscar. Though only two were nominated throughout the decade.
1933: "Three Little Pigs"
Classic cartoon featuring the song "Who's Afraid of the Big Bad Wolf" that was popular during the depression. Mickey Mouse "Building A Building" & Oswald Rabbit "The Merry Old Soul" (Lantz) were also nominated. Both are OK cartoons.
1934: "The Tortoise & The Hare"
Another great Silly Symphonies short. Several WB animators/directors have stated that Max Hare is one of the influences for Bugs Bunny.
"Jolly Little Elves" (Lantz) is pretty much mediocre.
1935: "Three Orphan Kittens"
"The Calico Dragaon" is the first MGM cartoon to be nominated, though an average cartoon from the era and also Disney's "Who Killed Cock Robin" were also nominated.
1936: "
The Country Cousin"
Honestly, "
Popeye The Sailor Meets Sinbad the Sailor" should've won. Other than tht it's one of my few favorite cartoons from the series, the 3D-esqe background (which Fleischer studios was known for) is stunning and had classic scenes from Popeye literally cooking a giant vulture and the catchy "Sinbad he Sailor" song.

"The Old Mill Pond", an MGM jazz cartoon with frogs was also nominated. It's an OK short though considered poltically incorrect by today's standards.
1937: "The Old Mill", use of the multi-plane camera
OK cartoon... though some parts tend to be boring
First Disney animated feature film "
Snow White & The Seven Dwarfs" won an honorary Academy Award" and was nominated for best musical score.
1938: "Fernidand The Bull"
"Brave Little Tailor" & "Good Scouts", while both also Disney, are better cartoons, IMHO.
1939: "The Ugly Duckling"
"Peace On Earth" (MGM) is a bit more darker and the rotoscope animation used for the battle scene is very convincing. Also find the "anti-war" message ironic considering that the US would enter WWII in a few years.
"The Pointer" (Disney) is the first cartoon to use the modern design of Mickey Mouse and is a fun cartoon with Mickey & Pluto out hunting and coming across a bear and Pluto trying to keep himself still when he spots quails.

"The Ugly Duckling" is a good cartoon, though the choices are tough.
"Detouring America" is a mediocre WB Tex Avery travel log parody.
Some cartoons that could've been nominated: "Porky In Wackyland", "I Love To Singa", "Minnie The Moocher", "Show White" (Betty Boop), and several better Disney shorts like "Mickey's Trailer" or 'Lonesome Ghosts".
