Christie's London has its Impressionist/Modern Evening Sale tomorrow night, Feb 2nd, and there are two van Gogh works on paper up for grabs.Lot 11 is a charcoal and pencil drawing done during Vincent's time at the asylum of Saint-Remy, "Six pines near the enclosure wall" (F1564 in the de la Faille catalogue). More specifically, this drawing is conventionally dated to a period after one of Vincent's attacks when he was still unwilling to leave the walls of the asylum to paint. Instead he did drawings inside the asylum's walled garden. The provenance can be traced back to Johanna van Gogh-Bonger, and the estimate is 600,000-800,000 British pounds.
Lot 17 is of historical interest because, dating to June 1882 and Vincent's time in The Hague, it's one of his earlier works. "The Iron Mill in The Hague" (F926) is gouache, watercolor, wash, pen and ink, and pencil on paper and has an estimate of 450,000-550,000 British pounds.
Thanks to former van Gogh seminar student Michelle for letting me know about this auction!!
