Wednesday’s ad is for Hamm’s, the Smooth and Mellow Beer,” also from 1947. It’s a fun post-war ad showing two couples having a backyard barbecue, with odd-looking wooden-keg mugs on (at the bottom at least) a brick-covered tray. One curious question. There are four people show in the back yard. There are four bottles of Hamm’s on the tray, along with an equal number of mugs. BUt unless one of them is Mr. Fantastic (from the Fantastic Four) then there’s a fifth person in the house not pouring themselves a beer. I want to know his or her story. Who is the unseen fifth wheel?
