This stamp was employed by Georges Jacob (1739-1814, maître in 1765) and François-Honoré-Georges Jacob (1770-1841) between 1803 and 1813, when they worked together under the company name Jacob Desmalter. Prior to that, François-Honoré-Georges was in partnership with his elder brother, Georges II (1768-1803), during which time the brothers used the stamp 'JACOB FRERES RUE MESLEE' (1796-1803).
