Isis and Osiris are two all-caps typefaces in the Sezession style. Isis was issued by Krebs by 1899. [1899 specimen] Poppelbaum carried Isis in two weights incl. Cyrillic, with Osiris being a variant of the (slightly) bolder weight distinguished by animated alternates and ligatures. [Wetzig 1926–40] Shown in Klimschs Jahrbuch 1901 as Iris [sic!] (light) and Osiris (bold). Also carried by Lehmann and Bauer [Reichardt 2011].
