Gothamburg is a blackletter or square gothic face. The shapes of many of the letters were inspired by sets of letters in Oscar Ogg’s The 26 Letters (Thomas Y. Crowell Company, 1963, 1948) illustrating the gothic style of the middle ages. The Plain and Thin versions differ not just in pen width, but also in pen angle. The Thin version has less contrast between the thin and thick strokes.
