Getting a Barbizon School painting valued: prices and value

Have you inherited a forest landscape, a rural scene or a study signed with a 19th-century name? Before selling it, you need to know what it is worth. Advice from Osenat, in Fontainebleau, at the heart of Barbizon country.19th-century paintings department

Does your painting belong to the Barbizon School?

The Barbizon School brings together the painters who, from around 1830 to 1870, worked from nature in the forest of Fontainebleau: Théodore Rousseau, Jean-François Millet, Narcisse Diaz de la Peña, Camille Corot, Charles-François Daubigny, Jules Dupré, Constant Troyon, Charles Jacque, and around them Rosa Bonheur, Henri Harpignies and Georges Michel. A few clues help identify a Barbizon School painting:

• The subject: undergrowth, oaks, ponds, rocks, heathland, forest paths, rural scenes, shepherds and herds.
• The handling: painting from nature, often on panel or paper for studies, in a palette of greens, browns and changing skies.
• Marks on the back: dealers’ or exhibition labels, wax seals, inventory numbers. They tell the story of the work.
• Studio stamps: after the death of several of these artists, their studios were sold at auction and the works marked with a stamp. The Étude de cheval brun above thus bears Rosa Bonheur’s signature stamp and, on the back, a wax seal reading “Vente Rosa Bonheur 1900”.

Signature and attribution: what you need to know

A signature alone does not authenticate a painting. The great names of Barbizon had many pupils and followers, and some, like Corot, are among the most imitated painters of the 19th century. In a French auction catalogue, the wording therefore has a precise meaning:

• the artist’s name alone: the work is given to the artist;
• “attribué à” (attributed to): the work is very probably by the artist, with a reservation;
• “atelier de”, “entourage de”, “école de Barbizon” (studio of, circle of, Barbizon School): the work is linked to the artist or the movement, without being given to the artist.

For major artists, the opinion of the author of the catalogue raisonné matters greatly. In our sales, the authenticity of several works by Théodore Rousseau and Georges Michel was confirmed by Michel Schulman, and that of a watercolour by Henri Harpignies by Dr Cappoen. Our expertise also draws on the De Bayser, Turquin, Maréchaux and Morin-Williams firms.

What gives a Barbizon painting its value

• The artist: the great names (Rousseau, Millet, Corot, Diaz, Rosa Bonheur) do not command the same prices as lesser masters or works simply catalogued “Barbizon School”.
• Technique and size: a finished oil is generally worth more than a sketch or a drawing, but a fine drawing by a great name remains sought after.
• The subject: a motif typical of the artist, such as Rosa Bonheur’s horses or Rousseau’s undergrowth, is in greater demand.
• Condition: restorations, relining, yellowed varnish or losses affect the price.
• Provenance: a studio sale, an old collection or a documented exhibition reassure buyers. Rousseau’s Le berger dans les Landes came from the collection of the Counts Doria.
• Authenticity: the opinion of the artist’s specialist or inclusion in the catalogue raisonné.

Frequently asked questions

How much is a Barbizon School painting worth?

From a few hundred euros for a small study or a painting catalogued “Barbizon School” to several tens of thousands of euros for a fine work by Rosa Bonheur or Théodore Rousseau. Only a valuation by a specialist can place your painting.

My painting is catalogued “Barbizon School”: is it worth anything?

Yes, these landscapes painted from nature have their admirers. Their price is generally more modest than that of a work attributed to an identified artist, hence the value of a careful examination of the signature, the style and the back.

Should I clean the painting before having it valued?

No. Clumsy cleaning can damage the paint layer and reduce the value. Show it to our specialist as it is.

Does the valuation commit me to selling?

No. The valuation is free and without obligation; you remain free to sell or keep your painting.
