I think the most shocking aspect of this advertisement is the blatant threatening tone toward the female, in terms of both the woman pictured and the women seeing the ad. Having studied advertisements from the WWII and post-war eras, I find this example from the 1930s to be particularly jarring, as the tone is considerably more menacing than anything I have previously seen. From a 21st century standpoint, this advertisement seems to convey an acceptance of spousal abuse toward women, in which wives are expected to fear the wrath of their husbands. Of course, at the time, however, those seeing the ad would likely view it as simply an illustration of a man's rightful dominance over his submissive wife. Regardless, we can clearly see that the ad uses the method of focusing on a woman's fear of her husband to sell the product, i.e. if she buys Drano, she will avoid her fear of being the object of her husband's anger.
