Cast as Aurora-Grotesk by C.E. Weber. “Aurora was based on [Neue Moderne Grotesk, ca. 1909] matrices from Wagner & Schmidt. This design was available from many different European foundries under different names. See also Normal-Grotesk (Haas), Edel (L. Wagner), Cairoli (Nebiolo), [Favorit (Otto Weisert)] etc. Inspired digital fonts like Dada Grotesk and Scout.” — Kupferschmid
As for post-metal revivals under the Aurora name, it appears that only condensed styles were available for phototypesetting. Bitstream issued two styles in digital format as Condensed and Bold Condensed.
