The Nazis indisputably had some of the best graphic artists and designers of the 20th century and indeed of all time.
Which just goes to show that the Greeks (and many others) were way offbase in their belief that Truth, Goodness and Beauty were the same thing.

Co-opted and perverted just as the Lutheran State Church of Germany was co-opted and perverted. Still, though, it's a correct statement. The quality of the aesthetic was unrivaled at the time. Uniforms, propaganda posters, public works, motor vehicles and machinery of war, all beautifully and even masterfully done. It remains a difficult thing for many to even be able to look at anything from the Nazi German era abstracted from the monstrosity of Nazism to this day, let alone when I was in design school. I spent some independent study time on the Bauhaus leading up to WWII. Well, Cuban and Soviet propaganda graphics, too. I was hoping to get at just why the visuals were so compelling. Heavy use of golden section, almost religious was my conclusion. Fold that into cultural touchstones and the easily led fall right into line right along with a fair number who should have known better.
