After our meeting at the Olympic Stadium, Erik S. pointed at the walls and asked me to ID the type. I failed, mumbling and stumbling through nervous guesses of Helvetica and Maxima. To be fair to myself, it’s a typeface that is no longer available in digital form: the elusive Unica. More info on Unica in this discussion and this discussion on Typophile and later in an article on Typographica.
