Plain Folks

This WPA poster illustrates the advertising technique - Plain Folks.  For the longest time, women were not supposed to have a modern day 9-5, but were expected to be housewives instead.  This meant that their "wifely duties" were usually subjected to keeping the house clean, taking care of the children, keeping themselves up to par, and preparing a nice meal for their husband to come home to after a "long and strenuous" day at work.  Here we see an ordinary woman mixing up some kind of concoction.  Her facial expression is almost too hard to read, but apparently she's not too thrilled.  It almost looks like she's saying, "Get off your butts and bake for these soldiers, women!".
