Wednesday’s ad is for Genesee Beer, which was founded in Rochester, New York, originally along the Genesee River, but in 1878 they moved up into Rochester proper. Their Genesee Cream Ale, in the simple green can, was one of our go-to beers when I was in high school. Since 2009, the brewery has been part of North American Breweries. This ad, from 1979, features a sci-fi theme, probably playing on the popularity of both Space Invaders and Star Wars, both huge at that time. Three spaceships, each a different can of Genesee beer, it probably made a cool poster at that time.
