Today we have radio and TV to get public health messages out but back in the early to mid-20th century, most government agencies relied on posters. During the First World War, public health officials made a point of educating through posters and leaflets.
The correlation between soldiers, sexually transmitted diseases, morale and social downfall were common. One theme in this group of posters is the implicit, and at times explicit, belief that it is the woman who is at fault.
This poster may be the only government statement calling women “bags”, at least implicitly. She is representative of the treacherous woman, a cigarette smoking, makeup wearing woman who is guaranteed to give men syphilis or gonorrhoea. The fonts and color emphasize the word TROUBLE.
