Are you Popular? (1947) [colourised]

A Coronet Instructional Films production.
One of the best examples of post-World War II social guidance films, with examples of "good" and "bad" girls, proper and improper dating etiquette, courtesy to parents, and an analysis of what makes some people popular and others not. A scream and a sobering document of postwar conformity.
