These vases appear in a watercolour by Jean-Baptiste Fortune de Fournier (1798-1864). This is extremely important in helping to date the works-of-art by André. Fournier was born in Ajaccio and died in Paris. He worked as a watercolourist for Napoleon III and exhibited at the Salons of 1843 and 1864. Eight interior views of The Tuilleries are recorded by him as well as a portrait of Napoleon III. He was awarded the Legion d'Honneur. The watercolour illustrating the Rothschild vases, as well as three others illustrating mostly jewellery apparently in the collection (see lots 50 and 56), was included in the sale of some of the contents of the château de Ferrières near Paris, the home of Baron James de Rothschild ans his successors, which was rebuilt by Sir Joseph Paxton in 1853-1863.
The design for a similar, but not identical, base of a vase by Vasters is in the collection of the Victoria and Albert Museum, London (E.3275-1919). In the opinion of Miriam Krautwurst, it is possible that Vasters restored an object for which he had made the design of the base, while the objects themselves appear more likely to be the work of Alfred André.
