Thursday’s ad is again for Schlitz, from 1958 (though parts of it are from previous years). Actually, it’s an advertising piece — a pamphlet or brochure — from their wonderful ad campaign, one of my all-time favorites, Schlitzerland. This piece, entitled “Schlitzerland, U.S.A., or how to entertain Schlitzfriends,” gives advice, along with songs, or how to throw various types of parties successfully. This is page twenty — the last page — with the tenth song, “Be a Schlitzer … Be Refreshed,” an original tune. Who’s thirsty now, after all that singing?
