"...How I should like to see what Gauguin and Bernard have brought along. I have a study of two yellowing poplars against a background of mountains and a view of the park here, an autumn effect in which the drawing is a little more naïve and more - home-felt." Letter from Vincent van Gogh to Theo van Gogh;
Saint-Rémy, 5 October 1889. (http://www.tfsimon.com/auvers-sur-oise.html)
