Two vases Cordelier 3eme grandeur fond blanc riches guirlandes de fleur and fruit par M. Jaccobber' are entered in the inventory sale records for the Sèvres magasin on May 28, 1844 (MNS, Archive, Registre Vv 4, folio 22, no 12; prix de vente 12.000 francs la paire) and immediately presented at the l'exposition des produits des manufactures royales au Louvre on June 3, 1844. It is most probable that these are the same pair.
