Otto Hupp’s blackletter font, released by Klingspor in 1911, took its inspiration from the then dominating Art Nouveau designs. Some of its capitals express this with their lovely swash forms, and make this fraktur font less stiff. Hupp Fraktur contains a bunch of usefull ligarures, and by typing ‘N’, ‘r’ and period you get an oldstyle numbersign by activating the Discretionary Ligatures feature.
