The logic behind this vintage ad is kind of wonky: Lady catches her hubs talking to "a strange woman" who turns out to be a corset salesperson. Affair paranoia diverted! "You see, Spirella lifts instead of squeezes," Mrs. Adams, the Corsetiere explains. And there are X-rays to prove it! Concludes the text: "If you feel and look tired and dragged down all the time, maybe you need a Spirella, too!" Laugh all you want, but today we have Spanx. (Click the picture to see full-sized.)
