This has to be one of my favorite pieces of vintage advertising. If you are truly a lover of advertising, you can appreciate the copy here. "Coca-Cola... a grateful invigorant without reactionary lassitude." What a fancy way of saying it gives you energy without the crash. My how times have changed.
Now they tell us to be clear and concise, because people don't care to read. Maybe this is proof that TV does really make us more stupidder (stupider or stupidder?? Studpider would be stu-pEYE-der, right? so it has to be stupidder for the short "i"...hmmmm?).[EDIT: Nevermind, it is "stupider." I looked it up. But really, I would argue for the double "d."]
This ad is dated June 1906. I got it from www.vintage123.com, a nice source of vintage ads (although it seems like they haven't updated in a long time).
