Being a professional artist is usually precarious from an economic standpoint. For that reason, I can't blame people like Domergue for latching onto a visual schtick that bring in the denarii. But I don't have to like the schtick.
Below are examples from his later (post-1940) work. Not all he did in those days looked quite like the images shown. What interests me is how similar those faces are. He apparently didn't have to do much research or thinking to create them.
