HWT Artz evokes bold early 20th-century European poster lettering. It was designed by Erik Spiekermann for his own print studio, P98a, in Berlin. The rounded corners and robust shapes stand up to the punishing world of backlit signs and bring a bit of levity to all cap texts. At smaller sizes, the softer shapes radiate friendliness without straying toward whimsy. The outside curves are largely clothoidal and always find the smoothest transition from straight to curved.
