FRENCH LANGUAGE The catalogue highlights the close relationship between the two Monet brothers and the role that Léon played as a promoter of the Impressionist painters at the beginning of their careers. It brings together a wealth of previously unpublished iconography, showing all the works in Léon's collection, including a large selection of pages from Claude Monet's first book of drawings. It also brings together photographs hitherto kept in family albums, together with rare archival documents and colour charts of fabrics with synthetic sheen, evidence of Léon's industrial activity.
