Buzz Feed just posted a collection of Second World War posters warning soldiers about the dangers of venereal disease from prostitutes and "procurable women".
Note how the first batch basically vilify the women as a secret enemy, while the last two put more onus of responsibility on male self-control and honour:
|If you sleep with a hussy, you're boning HITLER.|
|The pulp fiction cover style is actually kind of awesome.|
|This one has a Disney feel. She looks like the mirror in Snow White.|
|French girls: bags of trouble.|
|Wow. She really gets around.|
|Must... not... give in,,,|
|Friends don't let friends swive drunk.|
There are more examples, including homefront messages, here.
