We saw this beauty a few months ago in Museum De Fundatie in nearby Zwolle. It was one of the things that inspired me to re-start the blog actually. The painter is Dutch artist Leo Gestel (1881 - 1941). Along with Piet Mondrian and Jan Sluyters he was among the leading artists of Dutch modernism. This portrait is from 1914.
