The A-5 is understood as a growing archive of graphic design. In numerous illustrations, essays, and interviews, this book focuses on the outstanding personalities and important themes from the history of international graphic design. A5 is a collaboration between the visual laboratory at the Department of Applied Sciences Dusseldorf and Lars Muller Publishers. The magazine Twen, was published with a series of records between the years of 1961 and 1968, provided by the record label Philips. Each Twen issue at that time appeared with a record from the fields of jazz, classical, radio place, world music, or pop. Art Director Willy Fleckhaus used art by Karl Gerstner, Max Bill, Heinz Edelmann, and Gunther Kieser as the design for the album covers. The Forgotten, a collection of about seventy plates is a masterful example of the connection between music and graphic design. In cooperation with music archives and private collectors, this rare series is once again fully compiled and documented.
