Die Neue Gesellschaft issues 7-12, 1974. This was a German political magazine art directed by Helmut Schmid. These scans were obtained by AisleOne through the curators of Schmid’s work. I love the color coding, apparently this design continued through 1981, would love to see the full spectrum of covers. There’s some more info over at AisleOne and some larger scans at their Flickr page. If I was German I think I would spend most of my weekends digging through my parent’s house for stuff like this.
