The book celebrates 21 years of the Archetype Press and relates to the legal drinking age of 21. Each page is a typographic recipe for an alcholic beverage. It was produced by undergraduate students at the Art Center College Archetype Press under the direction of Gloria Kondrup. The Sackner copy of the book is the hard cover limited edition version. The other copies are soft cover books. Interview with Gloria Kondrup, Director of Archetype Press in The Dotted Line, official blog of Art Center College of Design: Interviewer: What do you see in the future for Archetype Press? Kondrup: "Unfortunately, the foundry metal type will eventually wear out, become lost or destroyed. But as education continues the digital march forward, the process of letterpress printing will hopefully remain a valuable technology in the study of typography and language, and conventional printing process will continue through the integration photopolymer plates that are digitally created. I see us moving toward a more fluid exchange between the technologies. And in another 21 years from now, or maybe even 100 years, someone might come across a phrase that has been inked and pressed into a piece of paper, and we will be remembered." -- Source of annotation: Marvin or Ruth Sackner.
