Grilli Type’s GT Americain use on this poster for a dance night in Bar 59, Luzern.
From Bar59 (translated from German):
What does “Doafri” mean? Well, nothing but the graduation party of the Luzern high schools, and subsequently pure party mood, pure joy and absolute feelings of happiness. Doafri certainly is not a party exclusively for soon-to-be ex-pupils. Everyone who is ready to party is welcome.
