As we’ve noted before, Sisley paintings are the ideal tonic for anyone suffering from a landscape impressionist deprivation. Alfred Sisley was, of course, the consummate Impressionist landscape painter: he was Captain Consistency of the Impressionists in his dedication to en plein air, never dabbled with the nude men and women (like Renoir and Pissarro) and he also stayed true to his Impressionist artistic roots – we’re no doubt sure he also never did dye his hair. His most famous works are series completed along the River Thames and landscapes Moret-sur-Loing and one painting that is causing waves in the Sisley world will soon be on auction for the first time ever.

We’ll admit a little fanfare is in order with the announcement that the Les Coteaux de la Celle-Sous-Moret, vus de Saint-Mammes, one of Sisley’s most amiable river scenes, will be publicly available to bid on for the first time since it was finished in 1884. Sotheby’s will sell it at their major London sales of Impressionist & Modern Art, which take place on February 8 and 9 next year (2012). Auctioneers have predicted it will sell for about £600,000-800,000, not an outrageous sum to pay for what critics consider the quintessence of his artistic ideals set in the Parisian countryside. The strength of Sisley’s brushwork suggests a mounting familiarity with neo-Impressionist beliefs, on top of his extraordinary talent for controlling paint.

If the asking rate of British Pounds is a little too hefty, what about a collection of three personal letters Sisley wrote? The snail mail goes on sale on December 13, 2011, at Sotheby’s New York. The manuscripts are expected to fetch between USD$6000 to $8000. In one letter dated 1872, Sisley writes of an impending trip to Paris to see Claude Monet about an idea of Edouard Manet: “si vous pouvez vous trouver a parais nour pourrons nous entendre avec Monet au Sujet d'une idee qui est venue a manet. Il s'agit d'un diner a offrir a durand-Ruel” the letter reads, which also hints at a dinner with their mutual dealer, Duran Ruel. Also contained in the collection is a letter to Pissarro dated 1883, where Sisley sends his apologies for neglecting to send an invitation to his cousin. The final letter is dated April 12, 1891, where Sisley writes to an unidentified gentleman regarding the sale of a painting.

Do you plan on becoming a famous painter sometime in the future? We’d recommend printing out your email account and filing it away. Sign a few pages, add a few doodles, or perhaps fingerprint some pages for the fun of it. Not only will it be a bit of creative release, but if your heirs are ever looking for some extra spending cash, they can liquidate some of the thoughtful assets you left behind. No doubt Sisley never imagined that hundreds of years after his death, people would be bidding on letters he wrote as an afterthought to his primary income, painting. The irony would be helping him roll in his grave.
