Tuesday’s ad is for Budweiser, from 1945. This World War 2 ad features a laboratory with a view overlooking the Anheuser-Busch brewery far below, meaning this is one seriously tall ivory tower. But this one seems to be an overview, or summation, of several of their previous ads about all the research they carry out to improve their beer, with lots of side benefits to general health and, of course, the war effort.
