The Mittelrheinisches Musikfest, or Middle Rhine Music Festival, took place in May 1925. It was organized in Trier, Germany, in cooperation with the cities of Saarbrücken and Coblenz (since 1926 spelled Koblenz), and directed by Heinrich Klapstein.
The cover and the title page of the program booklet feature a typeface that was issued only a year earlier: Messe-Grotesk halbfett from 1924 is an extension to Messe-Grotesk-Versalien, a black all-caps design that was first cast in 1921. The series by the AG f in Offenbach/Main was concluded in 1927 with an inline version. In the 1930s, Berthold sold it abroad under the name Advertisement Grotesque.
The design by Albert Auspurg is characterized by diamond-shaped middle bars (in E, F, H), triangular forms (A, i), and descending diagonals (K, M, R, S). Note the compact capital umlauts in the stacked and justified setting on the cover, and the ligature for ck (but not for ch, although there was one) on the title page.
