It's always fascinating to look back at print ads from yesteryears as they serve as a window into the past and what values and attitudes were acceptable back then. Even though I think you shouldn't judge work from the past with today's value (look up presentism), I'm going to do that anyway with some of the following vintage ads for your entertainment.
Get drunk for the country
These two ads from Boon Rawd Brewery contain a somewhat xenophobic attitude. The one on the left claims that their made-in-Bangkok beer contains no chemicals, unlike the ones imported across the sea. The right one is less subtle with a slogan that goes, "It's better to drink Thai beers instead of foreign ones. If not, then you don't support Thailand." There's no marketing tool more effective than guilt-tripping someone to buy your products with patriotism, right?
