The Seine, Henry Ossawa Tanner

Though not the subject matter for which he is best known, brilliant American painter Henry Ossawa Tanner, who spent most of his later career in France, painted a number of beautifully atmospheric and richly painterly views of Paris and the Seine.
I’ve had the pleasure of seeing this piece in person, and it’s just a treat.
