Apparently, the primitive toothbrush that a caveman -- or Napoleon, much the same thing in some respects -- would recognize is fashionable, trendy, and romantic for contemporary consumers. If not, why else would Pottery Barn and Anthropologie feature toothbrushes not seen since Gone With The Wind was a new film? Is there a secret and profitable market in hawking ludicrously outdated bad toothbrushes to modern retailers who think that good ones look gauche? Or do they import their props from Borneo, or what?
We all know that toothbrushes have moved on since Napoleon's time. He had a silver gilt one, monogrammed with the letter N (how bourgeois!) and stuffed with horsehair bristles, the bastard. You can see the front of it here, and the back as well.
