I’ve just come across this public information film from 1949 (or try here) about the post-war education reforms. With hindsight, I’m a bit ambivalent about the politics, but the sentiment is touching, and the quality of the animation is breath-taking.
Remember: this is a public information film. I was looking for a different one involving a certain Charley.
UPDATE: I’m trawling through the Public Information Film National Archive – it’s fantastic!
