Designed by Walter Wege for Berthold in 1931. Lettergieterij Amsterdam had it as Sirene, Jezynskiego as Faksymile, E. Reggiani as Stilo. A lighter Script-Signal and heavier Block-Signal were released in 1932. In 1934, a Deutsch-Signal with German Kurrentschrift letterforms was added. Only the original style is available in digital format.
Two forms of ‘r’ were offered, in roman and cursive forms, along with other alternates.
