I have to say that this has really piqued my curiosity. I would NEVER have thought to use Listerine as an aftershave. Since I was intrigued, I picked up a bottle of cool mint Listerine, today, and will give it a shot on my next shave. As an aside, I must say that I get a real kick out of these old ads. It seems laughable to us, now, that an ad would say to use Listerine as an aftershave for its disinfectant properties and that, if you didn't, you might actually DIE from a nick that got infected. I just find it hard to believe that people were actually that gullible back then.
