After the scholarly boycott, the Degas plasters and the resulting bronzes remain in limbo. It is now clear that they are not late 20th-century fakes, but the key question is when they were made. 

The experts believe the plasters were made after the Second World War and are, therefore, fairly far removed from the artist’s intentions, while those who commissioned the casts are convinced that they are much earlier and may well be from Degas’s lifetime. The story began two years ago, when a set of newly cast bronzes was unveiled at the Herakleidon Museum in Athens (The Art Newspaper, March 2010, p29). Earlier bronzes, which are in numerous museums, were cast from 1917 to 1936 and from 1958 to 1964 and were made via the original waxes, which survived after the artist’s death.

Two New York-based dealers discovered the plasters: Walter Maibaum, who runs Modernism Fine Arts and the Degas Sculpture Project with his wife, Carol Conn, and Gregory Hedberg, a consultant at Hirschl & Adler. The plasters were found at the Valsuani foundry, outside Paris, which had taken over the stock of the Hébrard foundry. Hébrard had earlier cast Degas’s bronzes for the artist’s descendants.

Leonardo Benatov, who owned Valsuani, agreed to cast a new set of bronzes for Maibaum. So far, 16 sets have been cast and rights have been acquired to cast a further 13. Their value will depend on whether they are accepted as authentic, but appraisers suggest that a set of 74 could be worth around $20m. On this basis, all 29 sets would be worth more than $500m.
