Streetcar Advertising Poster for Heinz Prepared Mustard, circa 1925

Henry J. Heinz rarely missed an opportunity to market his "57 Varieties" -- a catchy slogan he created despite offering a line of more than 60 packaged food products. A prolific promoter, Heinz aimed to reach consumers in stores, at home, and everywhere in-between. This colorful poster advertised Heinz Prepared Mustard to passengers riding in a streetcar.
