Designed in-house at J. Idźkowski i S-ka in Warsaw in the 1920s [Nowacki] and released in 1931 [Reichardt] in a single italic style (Cyklop kursywa). In Podstawy techniki wydawniczej (1967), Filip Trzaska shows 11 glyphs from an upright Cyklop antikwa, but the source of this sample is unclear. [Nowacki]

Digitally revived and expanded by Janusz M. Nowacki in 2007, in italic and upright styles (used for sample).
