This folded letter, dated 1843, was addressed to Monsieur Demion at the prestigious Collège Rollin, located on Rue des Postes, No. 34 in Paris. The envelope bears a clear red Paris circular date stamp alongside a boxed red P.P. handstamp indicating prepaid postage. The handwriting is elegant, typical of early 19th-century correspondence, and the letter was folded to serve as both message and envelope, a common practice before the widespread use of envelopes and stamps. The content, written in sepia ink, is a touching personal letter from a family member — signed "ta sœur Charlotte" — offering affection and advice, and expressing eagerness for more correspondence. Red wax seal remnants are still visible, and the letter shows the wear and edge notches consistent with transport and opening. Historically, this item represents the educational and postal culture of France during the July Monarchy era and provides insight into familial ties, etiquette, and written expression among literate citizens of the time. Estimate: "$40 – 60"
