I accepted the suggestion of placeboKatz and took a look at Destination Earth. It is a propaganda cartoon sponsored by the American Petroleum Institute, where a Martian explorer discovers the secrets behind the USA's prosperity: oil and free enterprise. The best of it is not the message, is the animation and the producer behind it: John Sutherland Productions.

John Sutherland was responsible for the production of several Disney's animations of 1930's and 1940's. The Animation Station Podcast made a very nice episode about him:

John Sutherland worked as a assistant director for Disney before opening John Sutherland Productions in 1944 with the encouragement of Walt Disney. They specialized in writing and producing animation/live-action films and supportive print material during the remainder of the war years.
Soon thereafter, Sutherland began turning out animated industrial and propaganda films and was a place many animators went during periods of inactivity at the other animation studios during the 40s and 50s.

His fifties production is composed basically by educational short films and propaganda with animation, many of them with a clear anti-communist slogan - very funny nowadays. I made a search to see what else that he produced was available at Internet Archive in public domain and the result was quite nice.
