Early 20s Well, we're glad someone does this. Wasn't really aware that this was a problem. But there was an understandable craze for "Sanitary" things back then; the word was used to connote purity, quality. It looks a bit dated today, but our contemporary antibacterial product fixation will look equally dated in a few decades.

(Note: this is a very old site, dating back to the late 90s; it's been redesigned a few times, but if it looks familiar, that's why. It used be called "The Fiche Tank," and collected ads from several decades. That's before I had sites devoted to different eras.)
