Friday’s ad is for “Hamm’s,” from the 1930s. This ad was made for Hamm’s Brewing, which was founded in 1865 by Theodore Hamm in St. Paul, Minnesota. At its peak, it was the 5th largest brewery in America, and operated facilities in five cities, including San Francisco, L.A., Baltimore and Houston, in addition to the original brewery in Minnesota. This one features a billboard with a beer being poured into a glass, with the tagline: “fully aged … Hamm’s Preferred Stock Beer!”
