There is a series of articles to look at the best of the public information films of the last 6 decades. Today it is Rolf teaching us to swim.
Rolf scores highly, but I'd like to see the Tufty club and their road safety ads, and the Green Cross Code man (aka Darth Vader).
If I never see the wailing 'Charlie the Cat' again it'll be too soon...! (All of these selections rather date me...)
