Vintage Porsche Poster Design

These great vintage posters commemorating Porsche's racing achievements were found at the Grain Edit blog: their design contains many elements of the Swiss Style pioneered by Muller-Brockmann, one of my favourite graphic designers.

The '66 poster was designed by Erich Strenger (I managed to find a little more information about him here), and the other is credited to 'Volz'. I'm not sure whether this is Strenger's design house, another design firm or the name of a designer—if anyone knows then please leave a comment, I'd be interested to find out.
