Anne Gruner Schlumberger, whose choices in selecting pieces was very eclectic, wanted to build a collection in which learned art would mix with popular art and where old and new objects would mix.
By the end of 2009, more than a thousand works and objects of art were identified and indexed, including paintings, sculptures, drawings, engravings, books of art and exceptional pieces such as furniture and clothes. The collection is kept in a secure area.
The five hundred and fifty-five works of art that make up the collection are divided into three groups of unequal importance :
The first group is formed of nearly seventy archeological sculptures which come from all five continents, with however two prevailing trends from the Mediterranean Greco-Roman area and Africa.
The second group comprises a set a hundred works, from the Middle Ages to the 19th century (paintings and sculptures)
Modern art is the main form of art in the third group, which comprises three hundred and ninety works (paintings, sculptures and furniture) from seventy artists. Amongst them, thirteen artist, including Victor Brauner, Anita de Caro, Max Ernst, Luis Fernandez, Diego Giacometti, François-Xavier Lalanne, Henri Laurens, Pablo Picasso, Yassilakis Takis and Roger Vieillard, have contributed more than tens works each.
This ensemble is comprised mostly of artists from the imaginary or surrealist schools of painting. It has an almost equal amount of paintings, sculptures, works on paper, drawings and engravings.
The collection also includes around sixty artists’ books, which are illustrated by twenty creators, and in which one may find three hundred and thirty nine original illustrations.
There were around a thousand pieces of Provence or rustic furniture that still need to be indexed, as well as a thousand artefacts, agricultural tools, urns, jars and all sorts of baskets.
In 2016, the collection was enriched with works by Pierre-Marc de Biasi: a triptych of concrete, Pierres d’Eclipse (1999) and a circular work, Table de la loi d’Eden (1998), gifts of the author, and a Talisman, monotype on paper (2001) acquired from the same artist.
