The logo is based on Motter Tektura. The P descender was elongated, and the e extended to connect to the following letter. In some applications, the double f gets a descender as well. Via this logo, Tektura even made it to the top of Hard’s church, among other places.
The photos were kindly provided by Triest Verlag. Earlier this year, Triest has published the long-awaited Motter biography, edited and designed by Elias Riedmann and titled Othmar Motter – Meister der Extrabold (“Master of the Extrabold”).
