Monday’s ad is for Michelob, one of the brands created by Anheuser-Busch as a draft-only beer in 1896. It was first packaged in 1961, and its distinctive teardrop bottle won a design award the following year. But that was replaced in 1967 “for efficiency in the production line,” but reverted to a traditional bottle in 2002. This ad is from 1968, and features a Dagwood sandwich with a full mug and half-bottle of beer next to it, with the tagline “In Beer, Going First Class Is Michelob. Period.”
