Vincent Van Gogh was a pretty good painter, of course, but he was also a great draftsman. Here’s one of his best drawings, a portrait of Joseph Roulin, who was Van Gogh’s postman during his period at Arles – and the guy who take care of Van Gogh after the ear-cutting thing. Van Gogh drew and painted many members of the Roulin family. These paintings and drawings are among Van Gogh’s best figurative works. And this drawing is one of the greatest ever.
