1. The frame-maker Pierre Cluzel had his shop at 33 rue Fontaine Saint-Georges, in Montmartre. See Frédéric Destremau, ‘Pierre Cluzel (1850-1894), encadreur de Redon, Pissarro, Degas, Lautrec, Anquetin, Gauguin’, Bulletin de la Société de l’Histoire de l’Art Français 1995, pp. 239-247.

2. As a result of the exhibition held in Restaurant du Chalet in November-December 1887 (see letter 640), Van Gogh exchanged his Sunflowers gone to seed (F 375 / JH 1329 ) and Sunflowers gone to seed (F 376 / JH 1331 ) for Gauguin’s On the shore of the lake, Martinique, 1887 (W252/W222) (Amsterdam, Van Gogh Museum) Ill. 100 . See Annet Tellegen, ‘Vincent en Gauguin’, Museumjournaal 11 (1966), pp. 42-45. Cf. also letters 653 and 736.

3. Gauguin had been staying since his return from Martinique in mid-November 1887 with Emile Schuffenecker, 29 rue Boulard. This street is located in the south of Paris, below Montparnasse, and was therefore quite some distance from Montmartre, where the Van Gogh brothers lived.

4. The art dealers Boussod, Valadon et Cie, for whom Theo worked, had their gallery at 19 boulevard Montmartre.
