Saturday’s ad is for “Rainier Beer,” from 1974. This ad was made for the Seattle Brewing & Malting Co., who made Rainier Beer, and was later known as the Rainier Brewing Company of Seattle, Washington. This one features a man with a mountaintop for a head and the tagline “Think Fresh.” It’s a weird one, to be sure, and it made me think of Frank Zappa’s song “Billy the Mountain.” But no sign of Ethel.
