FC Twente (Enschede, the Netherlands) introduced new shirt numbers in the summer of 2005. An original choice! The typeface that is used is either Ionic no. 5 (1925) or Excelsior (1931) or Corona (1941). These three typefaces were designed by Chauncey H. Griffith (1879-1956). Of course, his purpose wasn't to create shirt numbers. Griffith intention was to make a legible typeface for newspapers. And he succeeded; Ionic no. 5, Excelsior and Corona were – and still are – popular typefaces.
PS. A more close look at the Twente-numbers showed that 7 has a straight bottom line. So I had to reconsider my judgement: the typeface used by Twente isn't Excelsior/News 702, but Clarendon Bold (slightlycondensed).
