Hi,
I was wondering if anyone would be able to help me identify this beautiful Swiss-style sans-serif font from a 1981 art exhibition poster from the Museum für Gestaltung.
Thank you !

I'm probably wrong but I see Paul Renner's [[http://www.myfonts.com/search/futura|Futura]], Demi or Bold...

@Ryuk I think you're right. Oh well, that's embarassing... I guess I could've figured that out myself... Thanks!
