The only thing that gives me pause are the featureless faces. There is also a similarity of the windmill itself, to his other windmill paintings.
I'm still looking, though - trying to find out who it could be. It might be an unknown - one of those men at the atelier.
If you lay out all his paintings, in a row, chronologically - this one would come as a surprise.
I'm also wondering why Van Gogh didn't sign this painting? And if he signed all his others?
I just noticed that the curator himself thinks the painting was unusual for a Van Gogh.
I would like to know what markers they used to authenticate it, other than the art store stamp and the pigments. What about stylistic markers?
