The cover for the KPFA Folio is pictured here. It features the Köln (Cologne) cathedral seen within a span of the San Francisco Golden Gate bridge. Both bridge and church are resting on a pair of KPFA tape reels  The German word for 'bridge' is Die Brücke and it represents the vision of this acoustical alliance between San Francisco and German radio.  Bill Fontana would later implement the theme by mounting a sonic mix of San Francisco, Golden Gate sounds, with the Rhine River, which flows through Köln. It was heard simultaneously on the waterfronts of both cities.
