Little is known of Van Gogh's activities during the two years he lived with his brother, Theo, in Paris, 1886–1888. The fact that he had painted "Sunflowers" already is only revealed in the spring of 1889, when Gauguin claimed one of the Arles versions in exchange for studies he had left behind after leaving Arles for Paris. Van Gogh was upset and replied that Gauguin had absolutely no right to make this request: "I am definitely keeping my sunflowers in question. He has two of them already, let that hold him. And if he is not satisfied with the exchange he has made with me, he can take back his little Martinique canvas, and his self-portrait sent me from Brittany, at the same time giving me back both my portrait and the two sunflower canvases which he has taken to Paris. So if he ever broaches this subject again, I've told you just how matters stand."
