I often think about why this country seems so fouled up when it comes to guns & sex, among other things. This popped up on my homepage today & it sure explains a lot. This ad is from 1918 & it promotes Erector (heh, heh) plus other "toys" by the same company. A nurse's outfit, now that really creeps me out, given the other toys advertised.
Full disclosure, I did receive an Erector set one xmas. My family was visiting my mother's youngest brother in Waterloo, IA. I remember building something. Clearly, however, engineering was not in my future. I never, ever, got a nurse's outfit. I mean it. I did marry a nurse, but she never, ever wore a nurse's outfit, anywhere, especially in our house. I mean it.
