Catalogue de tableaux authentiques des maitres sous les noms desquels ils sont annoncés, et choisis dans plusieurs collections célèbres, par M. Didot : avec gravures au trait, d'après les portraits de Guillaume Tell et de Ninon de Lenclos, faisant partie de cette collection
This 1814 Paris catalogue, printed by Leblanc, lists authenticated paintings from famous private collections assembled by M. Didot, with line engravings after portraits of Guillaume Tell and Ninon de Lenclos. The two pictures are small circular stamp-like seals showing a standing draped figure with a hat beside a stone pedestal and an eagle-like bird, framed by a ring of lettering reading 'DE LA SEINE' and decorative border ornaments. A designer could take the compact roundel framing, the classical figure and the ornamental ring lettering as a model for emblem or seal design.
