Gutfreund was a Czech sculptor working in the early 20th century. He has worked in a number of different styles but that all seem to be intentionally stylised or abstracted in some way. He seems to be primarily interested in shape and surface quality (like me) as he seems to play around with that a lot. I think both his smooth flattened style and his more cubist wavy style could look good in digital/net formats an so it is maybe work me making some faces in a similar style to him?
