Cut in-house and first cast in 1929 [Berthold Musterkartei DIN 16507] or, more likely, 1936 [Klimsch Druckerei Anzeiger]. Registered as Plastika in June 1936 [VdS]. Advertised as a shadow companion to Berthold-Grotesk (1928), together with Umbra, although a number of glyphs are clearly different in structure. No lowercase. Also sold (not cast) by Amsterdam as Duplex (or Duplex kapitalen) from 1936 on. [Lane & Lommen]

Berthold offered a phototype version. [Berthold 1974]
