Anybody for a great coffee flavor?
OK. This concerns you. We have a product called Coffee Blanche. It has the full spectrum of coffee flavor and aroma found only in the highest quality coffee. Coffee Blanche is a hydro-alcoholic extraction of carefully selected, aged coffee beans. It’s water-white, and all the bitter notes have been completely eliminated. We developed Coffee Blanche especially for liqueur, but it’s the perfect ingredient for icings, confections, ice cream, pharmaceuticals, and any other product requiring an exceptional coffee flavor. If Coffee Blanche sounds like what you’ve been looking for, write us on your letterhead and we’ll send you a sample and Technical Directive. That goes for anybody.

(Marjan Stuckart)
advertisement is very simplistic in appearance and text. does this convey a general trend towards simplicity in advertising during this time period or is this unique to Ritter International?
