Friday’s ad is yet another old one for Schlitz, this one from 1912, and is, like the last two, touting brown bottles as the best package for beer. I have to admire the effort to educate consumers to think about the package their beer came in, something craft brewers did again roughly 70 years later. And I love this bit of chutzpah. “As civilization advances — so do the sales of “Schlitz in Brown Bottles.”
