Wednesday’s ad is for Pilsner Urquell, from what looks to be the 1950s based on the style of illustration on this postcard. Showing a geeky-looking mathematician in front of a blackboard filled with a calculation. I wonder if it’s just gibberish or if it really does express something mathematically — gravity perhaps? But the idea is that if it weren’t for math we wouldn’t be here on planet beer to enjoy our Pilsner Urquell.
