In the shattered aftermath of the Great War and the emergence of Modernism during the first 20 years of the 20th century, painters were faced with a What The Devil Do We Do Next situation. Various this's and that's popped up including a German movement called New Objectivity (Neue Sachlichkeit).
It was rather ill-defined, as this Wikipedia entry indicates. There was the gross (pardon the pun) , crudely-drawn work of George Grosz. And then there was the calmer, less anger-fueled work of Christian Schad, who I'm likely to return to in future posts.
Schad fell into the distorted, cartoon-like New Objectivity practice, but not very far. What I find interesting is that his work sometimes resembles early paintings by untrained or poorly trained American painters. I doubt that he was aware of this American art, so what we have is simply a striking coincidence and not inspiration. Take a look:
Graf St. Genois - Christian Schad, 1927
Man Holding a Large Bible - Anni Phillips, c. 1826
Bettina - Christian Schad, 1942
Girl With Bird and Cage - Unknown artist, c. 1735-40
