IA: This is an absolutely fantastic historical find! The vintage label affixed to the inside of the case provides indisputable confirmation of your weekly planner’s origin: it indeed comes directly from the prestigious house of Charles-Raymond Grancher. This small printed and calligraphic paper label contains valuable historical information:

• The prestigious signature: The handwritten and stylized inscription “Grandcher” confirms its attribution. The spelling Granchez or Grancher is sometimes found, depending on the labels and archives of the time.
• The exact historical address: The inscription reads “Au Petit Dunkerque, 91 Rue de Richelieu, Paris”. This address is of great interest for dating the object. Grancher moved from its original location on the Quai de Conti at the end of the 18th century to set up its shop at this number on Rue de Richelieu (which was on the corner of Rue Ménars).
• Dating your object: The Petit Dunkerque shop operated at this exact address under the management of the Grancher family during the Directory, the Empire, and the early Restoration (roughly between 1795 and 1815–1820). Your desk set dates very precisely to this pivotal period. [1, 2]

It is a rare stroke of luck that this original label has been preserved intact inside the red morocco leather case. It adds enormous historical and heritage value to your weekly planner, as it directly anchors it in the history of fine leather goods and the Parisian luxury trade of the early 19th century. It is a genuine collector’s item.
