Badmovies.org has a clip from an anti-VD training film from 1942 that’s pretty interesting, too:

The clip as at the bottom of the review (site owner is touchy about hotlinking directly to the clips).
Back in the 80’s we actually had a 16mm copy of that film at my Navy command!!!
Ned Beatty was in the film!
Now I know where he learned to squeal like a pig!
