Where most fonts are available in varying weights, 52-Kfx is a family consisting of 3 heights; High, Mid and Low. These offer the typographer a full palette, Low is readable for setting copy while at the opposite end High is better suited for display—names, headlines and logotypes. 52-Kfx has a sophisticated and elegant period feel with clean, modern lines that remain relevant for contemporary application. Exaggerated ascenders and descenders of the lowercase and a tall cap-height give it a lofty stature while the low x-height keeps characters grounded. The spacing and lyrical rhythm are perfectly in sync and epitomized by the fluidity seen in the ligatures.

Barnhard Brothers and Spindler called this typeface Congo when it appeared in their circa-1910 type catalog. The design is characterized by strong Art Nouveau influences, tight spacing and a large x-height.
