Plates very clean and bright.Maurice Edmond Charles Rothschild (1881-1957) financed and organized (together with Henri Neuville) a collecting expedition in East Africa; travelling from Djibouti, across Eritrea to Ethiopia and Kenya. The specimens were presented to the Muséum national d'Histoire naturelle. A large number of entomologists, including Charles Rothschild, worked on the specimens and their descriptions were published in the first two volumes of this publication. Only 400 copies were printed. Spoiler alert: A complete set of 100 (extra large) plates of this expedition will be offered in a deluxe paper catalogue, featuring the rarest and never before offered books I have in stock. To be issued early next year (1925)!
