I had one as a teacher in 3rd grade (1957).
The elderly nun we had for the first semester became too ill to continue and was replaced by a 20-something girl from Italy who looked like Gina Lollobrigida.
THAT was quite a change....
The infamous 1950’s pinup girl Bettie Paige graduated from a teachers college in Tennessee and attempted to teach high-school.
Built like she was, the stares, catcalls, and other intense attention of adolescent boys drove her out of the profession.
