That Lux Ad...
...Was a nice try, but putting a vac under a Christmas tree actually didn't sit well with housewives of the era. I remember one of my female relatives getting a new iron as a Christmas present. Once that got around, most of the men in the family were warned that if they ever did such a thing, they'd be lucky to escape without injury, LOL. There was a fine line about household stuff for Christmas; if it was fun and convenient, it was okay. If it represented drudgery, it wasn't. Automatic toasters, electric frying pans and electric can openers were fine. Vacuum cleaners, irons, etc. were not. With some things, it depended on circumstances. A new sewing machine was welcome if the lady of the house sewed for her own pleasure. If it was needed to keep up with the mending for seven children, it was not gift material.
