I love this description of Electra, one of my favourite typefaces, from Sibylle Hagmann,
W.A.Dwiggins developed Electra, also labeled as Experimental 55 at the Linotype offices, between 1930 and 1939. As Hagmann explains, “with his desire to create a typeface that is ‘warm, full of blood and personality’, Dwiggins succeeded beyond that. I especially enjoy the shapes of the lower case ‘a’, ‘g’ and the beautiful ‘r’, a form that I sometimes find challenging to design. Electra’s letter design foreshadowed his ‘M-Formula’ and remains one of my favorite American-made book typefaces.
