Looks close to this, except they shaved off some corners:
It kinda looks like a Hermann Zapf font. Identifont didn't find it either. Almost none of the things it asked are in your sample. Is there something else that is printed with it in the magazine perhaps?
EDIT: It's "Fago NS" (custom) created by Ole Schäfer. The non-custom one is available from FontFont.com
