Anthony, I saw your post on the main board asking the background of the Yuengling's set. Yuengling is the oldest brewery in America, and produced ice cream (along with non-alcoholic beer) during prohibition. The cards were used to market the ice cream during the ban on beer. Yuengling continued to produce ice cream well into the 1980s. The company has just recently returned to selling ice cream under its label, although it is manufactured by a local creamery.
