4. Van Gogh must have written to
Gauguin about the art dealer
Georges Thomas;
see letter 617, n. 8, and
letter 640, n. 16. Louis Nicolas André Thomas, Duke of Bojano, was the managing director of the
Compagnie du Soleil insurance company and a collector. His collection of 118 works was sold at auction in 1882. By the dealer near Place Vendôme, Gauguin probably meant the paint supplier and art dealer
Jean Joseph Thomas, who had a shop at 235 rue Saint-Honoré until 1887. See
Correspondance Gauguin 1984, p. 482 and exhib. cat. Paris 1988, p. 347 (n. 124).
