This is a "Portrait of Père Tanguy" by Vincent van Gogh and is hanging at Musée Rodin in Paris. It was painted in 1887 and is one of three paintings of Julien Tanguy by van Gogh. Tanguy was a paint grinder, he sold art supplies and was an art dealer. Personally I think he became an art dealer by default because the artists who came to him for supplies, couldn't pay him so he accepted their artwork as a form of payment. The Japanese prints in the background of this painting were also sold in Tanguy's shop and they greatly influenced Vincent van Gogh's painting style.
