Digging thorugh some old copies of the British weekly Everybody's, I found the above article on censorship in American animated cartoons. The article dates from 15 April 1939 when the Hays Code was being strongly enforced on Hollywood's output and as rigidly applied to cartoons as it was to live action movies.
Looking around to find a little more information, I discovered that the article wasn't original but based on an feature that had appeared a few months earlier in the American Look magazine (17 January 1939), a scan of which I found at the Cartoon Brew website.
As you can see, the original runs more examples than the version that appeared in Everybody's, although Everybody's was able to run some images with additional colour. The feature was put together with the aid of Looney Tunes producer Leon Schlesinger, who was instrumental in bringing characters like Porky Pig, Daffy Duck and Bugs Bunny to the big screen. Some of the images are taken from cartoons--the hula-dancing mermaid is from the 1935 Merrie Melodies cartoon Mr. And Mrs. Is The Name, which was one of the first cartoons to use the tag-line "That's All Folks" which was to become a familiar phrase at the end of Looney Tunes cartoons.
Everybody's, like many general magazines in the UK, made plenty of use of cartoons, some of which I'll post over the next few days.
