Let me start by saying that all these images are rated G; they're pretty tame by all accounts. I just find it interesting that in nearly every catalog I paged through from the late sixties and seventies had a woman in a state of undress in the bed & bath section.
I can understand the rational for it - you want to show the products in use the same way you'd show the clothing. Also, you don't want to be too realistic and show some pasty heavyset man on the throne; a young woman in a bubble bath is probably a much better option.
Therefore, I'm not sure this really qualifies as an example of the "sex sells" principle; however, it's definitely treading the grey area between benign product presentation and cheesecake sales tactics. Either way, they're interesting to look at if only for the vintage decor. Click the icon below and enjoy!
