The original design came from Berthold Herold typeface, designed by Hermann Hoffmann during 1913 (Art Nouveau style) in Germany. This project started from flyer printed during 1947 with movable type, the specimen was scanned as a source to development some of the uppercase letterforms. However the most unusual and tricky element from this sample is the leg from the uppercase (R) which is different from the original Herold design, until now I didn’t found where this version originally came from. This font family only contain the bold weight, but there are also a stencil and expanded versions available.
