Cyklop is a sans serif typeface with a highly modulated stroke so it has high typographic contrast. The vertical stems are much heavier then horizontal ones. Most characters have thin rectangles as additional counters giving the unique shape of the characters. The typeface was designed in the 1920s at the workshop of Warsaw type foundry "Odlewnia Czcionek J. Idzkowski i S-ka".
Cyklop was heavily used for heads in newspapers and accidents prints. Typesetters used Cyklop in the inter-war period, during the occupation in the underground press. The typeface was used until the beginnings of the offset print and computer typesetting era. Nowadays it is hard to find the metal types of this typeface.
